NTRODUCTION TO COMPUTER PROGRAMMING Loop as repetitive statement,
- 2. INTRODUCTION TO COMPUTER PROGRAMMING 1) Loop as repetitive statement, For loop/statement. 2) While loop statement and do while loop statement. 3) Variable Types, Data types, ranges and width.
- 3. For loop or For statement • It is the construct to repeat a body to be executed upto a number of times depending on condition. Syntax: for(initialization;checking;increment) { // body of for loop }
- 4. Program to generate numbers 1 to 100 #include<stdio.h> void main(void) { int counter; for(counter=1;counter<=100;counter++) { printf(“%d=”,counter); } }
- 5. Program to generate Hello Quest message 100 times #include<stdio.h> void main(void) { int counter; for(counter=1;counter<=100;counter++) { printf(“Hello Quest”); } }
- 6. While loop Syntax: initialization while(checking) { // body of for loop increment }
- 7. Program to generate numbers 1 to 100 #include<stdio.h> void main(void) { int counter=1; while(counter<=100) { printf(“%d=”,counter); counter++; } }
- 8. Program to generate Hello Quest message 100 times #include<stdio.h> void main(void) { int counter=1; while(counter<=100) { printf(“Hello Quest”); counter++; } }
- 9. do-while loop Syntax: initialization do { // body of for loop increment } while(checking);
- 10. Program to generate numbers 1 to 100 #include<stdio.h> void main(void) { int counter=1; do { printf(“%d=”,counter); counter++; }while(counter<=100); }
- 11. Program to generate Hello Quest message 100 times #include<stdio.h> void main(void) { int counter=1; do { printf(“Hello Quest”); counter++; }while(counter<=100); }
- 12. • Technical difference among for, while and do-while loop • Write a program in C using loop to generate even numbers from 1 to 100 • Write a program in C using loop statement to generate odd numbers from 1 to 100 • Write a program in C using loop to generate even numbers from 100 to 1 • Write a program in C using loop statement to generate odd numbers from 100 to 1 • Write a program in C using loop statement to generate table of any number • Write a program in C using loop statements to generate 1 one time, 2 times 3….. Upto 10 ten times 1 2 2
- 13. • Write a program in C using loop statements to generate 1 one time, 2 times 3….. upto 10 ten times 1 2 2 ….. 10 10 10 10 10 10 10 10 10 10 • Write a program in C using loop statements to generate 10 ten times, 9 nine times….. upto 1 one time 10 10 10 10 10 10 10 10 10 10 9 9 9 9 9 9 9 9 9 … 1
- 14. • Write a program in C using loop statements to generate (a) * ** *** **** ***** (b) ***** **** *** ** *
- 15. Data types • short int (short) • unsigned short int (unsigned short) • char • unsigned char • signed char • int • unsigned int(unsigned) • long int(long) • unsigned long int(unsigned long) • float • double • long double
- 16. Data types Ranges of values that can be stored in variables of these types will depend on the compiler you are using, but on an IBM PC’s and Borland turbo c compiler the ranges are: • short int -128 to 127(1 byte) • unsigned short int (unsigned short) 0 to 255(1 byte) • char 0 to 255 or -128 to +127(1 byte) • unsigned char 0 to 255(1 byte) • signed char -128 to +127(1 byte) • int -32768 to +32767(2 byte) • unsigned int(unsigned) 0 to 65,535(2 byte) • long int(long) -2147,483648 to 2147,483647(4 byte) • unsigned long int(unsigned long) 0 to 4,294,967,295(4 byte) • float single precision floating point(4 byte) • double double precision floating point(8 byte) • long double extended precision floating point(10 byte)
