Introduction

Coding for be,ginne,rs is a comple,te, and authe,ntic guide, for stude,nts who are, de,te,rmine,d to le,arn the, be,st programming approache,s, te,chnique,s, and me,thodologie,s. as the, software, industry is update,d with the, late,st coding language,s and tools e,ve,ry day, it is mandatory to adopt ne,w skills and te,chnologie,s to survive, in the, compe,titive, marke,t. re,ading has always be,e,n a vital re,source, for stude,nts and le,arne,rs as the,y can improve, the,ir pe,rformance, and output by imple,me,nting the, late,st te,chnique,s and programming me,thodologie,s.

This book is a succe,ssful programming manual cove,ring all of the, major programming language,s, syntax, and be,st practice,s that are, suitable, for both be,ginne,rs and profe,ssionals. be,fore, e,nte,ring into the, programming world, the,re, are, se,ve,ral important factors that ne,e,d to be, looke,d at in orde,r to de,ve,lop sharp proble,m solving and analytical skills. the,re,fore,, this book targe,ts novice, programme,rs and has be,e,n update,d with solutions and answe,rs to almost e,ve,ry que,stion you might have, about java, sql, c, c++, c#, python, html, and css.

I always e,mphasize, the, acquisition of basic knowle,dge, and skills. this book will not make, you a programme,r in just one, hour or ove,rnight, but it will build a solid foundation for your programming care,e,r. afte,r re,ading this book, your basic knowle,dge, of programming will incre,ase,, as will your proficie,ncy in any programming language,.

Chapte,r one,: what is programming?

Ge,ne,rally, programming is re,fe,rre,d to as a se,t of instructions that the, compute,r utilize,s to comple,te, ce,rtain tasks. this is also known as coding. be,fore, de,lving into an in-de,pth discussion, you must be, we,ll aware, of how programming works and how the, se,t of instructions are, proce,sse,d by the, compute,r. whe,n you are, able, to follow the, corre,ct approach of writing compute,r programs, it can be,come, quite, e,asy to imple,me,nt functions, ope,rators, and syntax for any language,. more,ove,r, programming is a way to communicate, with compute,rs through binary language, for which programme,rs ne,e,d to unde,rstand high le,ve,l and low-le,ve,l language,s including syntax as we,ll.

In orde,r to solve, a proble,m with a compute,r, use,rs are, re,quire,d to pre,se,nt the, solution for the, proble,m through a se,t of instructions which can be, utilize,d to e,xe,cute, the, program. as a program is a colle,ction of instructions that are, re,quire,d to solve, a proble,m, appropriate, state,me,nts and functionality must be, adde,d in orde,r to achie,ve, the, de,sire,d outcome,. for e,xample,, if you are, give,n the, task to de,ve,lop a program to add two inte,ge,rs (numbe,rs), the, se,t of state,me,nts that will pe,rform the, addition ope,ration will be, known as the, program. the, algorithm for adding two inte,ge,rs will be, e,xpre,sse,d through the, state,me,nts of a particular compute,r language, like, c++, c, c# or java. if the, program is not able, to e,xe,cute, prope,rly, the,re, might be, a proble,m with your algorithm or syntax be,cause, the, compile,r or e,ditor will be, unable, to e,xe,cute, the, program if the,re, are, any type, of e,rrors or syntax mistake,s.

Programming can be, be,tte,r le,arne,d through practice, and writing code, rathe,r than le,arning long me,thodologie,s or comple,x te,chnique,s. although it might se,e,m like, a fun activity at the, start, it can also turn out to be, time,-consuming and frustrating if you are, not following the, corre,ct approach. furthe,rmore,, this book will make, it e,asie,r for be,ginne,rs to choose, the, most suitable, programming language,s and e,nte,r the, world of compute,r programming without much hassle,.

Proble,m solving with compute,r programming

In e,sse,nce,, a compute,r program is suppose,d to solve, a spe,cific proble,m by following a se,t of instructions. pe,ople, can write, a program by following multiple, te,chnique,s and approache,s. in orde,r to solve, a proble,m, you ne,e,d to de,te,rmine, the, code, flow and fulfill the, re,quire,me,nts ste,p by ste,p to achie,ve, the, de,sire,d output. in some, case,s, your compute,r program may not work e,ve,n afte,r hours of struggle, be,cause, of inappropriate, syntax or flow for which you ne,e,d to focus on the, se,que,nce, of instructions and compute,r programming language, re,quire,me,nts.

Using this e,xample, of pre,paring a woode,n table,, you would ne,e,d to write, down the, instructions as follows:

Ge,t the, most suitable, pie,ce,s of wood re,quire,d to make, the, table,.

Ge,t the, e,sse,ntial tools and e,quipme,nt that will be, use,d during the, proce,dure,.

Join the, pie,ce,s and build your table,.

Polish the, e,nd product to make, it look attractive,.

Whe,n giving such instructions to the, compute,r, you ne,e,d to be, more, spe,cific and pre,cise, be,cause, a compute,r cannot pe,rform ope,rations on its own. as it is cre,ate,d to follow instructions, your compute,r program should always follow an incre,me,ntal approach in orde,r to achie,ve, the, de,sire,d outcome,.

On the, topic of the, natural language, of a compute,r, the,y are, unable, to unde,rstand human language, and the,re,fore,, we, ne,e,d to communicate, with the, syste,m through anothe,r language, calle,d binary code,. binary code, is made, up of a se,rie,s of 1s and 0s and is the, natural communicating language, of compute,rs. in orde,r to he,lp the, compute,r, unde,rstand human language,, we, use, translators and e,ditors for writing programs. translators have, the, capability to conve,rt the, source, code, into the, machine,’s language,.

The,re, are, multiple, type,s of translators known as inte,rpre,te,rs, compile,rs, and asse,mble,rs. inte,rpre,te,rs are, ge,ne,rally use,d to inte,rpre,t language,s which are, the,n proce,sse,d line, by line, to run the, final program. more,ove,r, any syntax e,rrors or mistake,s are, also outline,d by the, inte,rpre,te,r so the, programme,r can cle,ar out the, mistake,s and e,xe,cute, the, program.

With the, he,lp of compile,rs, the, source, code, is conve,rte,d to binary code, through a compilation proce,ss and is the,n e,xe,cute,d to de,live,r the, output. if the,re, are, no e,rrors or mistake,s in the, source, code,, all of the, line,s are, translate,d and e,xe,cute,d at once, by the, compile,r. more,ove,r, compute,r programs are, also known as apps (application or application software,) and are, tailore,d to the, e,nvironme,nt or platform the,y are, de,signe,d to run on. apps are, diffe,re,ntiate,d in the, cate,gorie,s of de,sktop
