C Program to Find Size of int, float, double and char of Your System

C Program to Find Size of int, float, double and char of Your System The size of a character is always 1 byte but, size of int, float and double variables differs from system to system. This program will compute the size of int, float, double and char of you system using sizeof operator. The syntax of size of operator is: temp = sizeof(operand); /* Here, temp is a variable of type integer,i.e, sizeof() operator returns integer value. */ Source Code /* This program computes the size of variable using sizeof operator.*/ #include...

C Program to Demonstrate the Working of Keyword long

C Program to Demonstrate the Working of Keyword long Keyword long is used for altering the size of data type. For example: the size of int is either 2 bytes or 4 bytes but, when long keyword is used, the size of long int will be either 4 bytes or 8 bytes. Also, you can use long long int. The size of long long int is generally 8 bytes. This program will demonstrate the size of keyword long for my system. It may be different in your system. Source Code #include <stdio.h> int main(){ int...

C Program to Find ASCII Value of a Character

C Program to Find ASCII Value of a Character Every character in C programming is given an integer value to represent it. That integer value is known as ASCII value of that character. For example: ASCII value of 'a' is 97. Here is the complete list of ASCII value of characters in C programming. When a character is stored in variable of type char, the ASCII value of character is stored instead of that character itself character itself. For example: If you try to store character 'a' in a char type variable, ASCII value of...
