Difference between long int and long long int in C/C++

Assigning multiple characters in an int in C language

Last Updated : 30 Apr, 2018

Consider the following C program.

C

#include <stdio.h>
int main(void)
{
    int a = 'd';

    printf("%d\n", a);
    /*OUTPUT - 100 (ASCII Code for character d)*/

    int b = 'dd';
    printf("%d", b);
    /*OUTPUT - 25700 (Explanation in detail given below)*/

    return 0;
}

Output :

100
25700

We can easily guess that the output for 'd' is 100 as 100 is ASCII value of character 'd'. Let us consider below line

int a = 'dd'

(%d, a) prints 25700 as output 01100100 01100100 (Binary of 100 100) Assuming int is of 2 bytes, starting byte is occupied by first character 'd' and second byte by second character 'd'. Therefore overall binary involves 0110010001100100 i.e 2^14 + 2^13 + 2^10 + 2^6 + 2^5 + 2^2 = 25700. Now guess the output of following code.

C

#include <stdio.h>
int main(void)
{
    int b = 'de';
    printf("%d", b);
    return 0;
}

Storage of integer and character values in C

Integer and character variables are used so often in the programs, but how these values are actually stored in C are known to few. Below are a few examples to understand this: Taking a positive integer value as char: C #include <stdio.h> int main() { char a = 278; printf("%d", a); re

Interesting Infinite loop using characters in C

We have already studied how a " for loop" works. Look at the following program: C int main(){ int i; for(i = 0; i < 128; i++){ printf("I am %d\n", i); } return 0; } In the above loop, the printf() statement will be executed 128 times. Now, look at the following program: C int main() { char i; for

Data type of character constants in C and C++

In C, data type of character constants is int, but in C++, data type of same is char. If we save below program as test.c then we get 4 as output (assuming size of integer is 4 bytes) and if we save the same program as test.cpp then we get 1(assuming size of char is 1 byte) C++ // C++ program demonst

INT_MAX and INT_MIN in C/C++ and Applications

INT_MAX and INT_MIN are predefined macros provided in C/C++ to represent the integer limits. Depending upon the compiler and C++ standard, you may be required to include the header file <limits.h> or <climits> in your C or C++ source code, respectively. So it is advisable to include this

Difference between long int and long long int in C/C++

All variables use data type during declarations to restrict the type of data to be stored. Therefore, we can say that data types are used to tell the variables the type of data it can store. Whenever a variable is defined in C++, the compiler allocates some memory for that variable based on the data

Difference Between Unsigned Int and Signed Int in C

Integers are typically stored as 32-bit values, but in some environments, they may contain 16-bit values (or even a different number, usually the product of two powers). For example, let's examine 4-bit integers. They are small but can help illustrate a point. Signed int can represent both positive

Differentiate printable and control character in C ?

Given a character we need to find if it printable or not. We also need to find if it is control character or not. A character is known as printable character if it occupies printing space. For the standard ASCII character set (used by the "C" locale), control characters are those between ASCII codes
