C program check whether a number is even or odd

Posted on December 17, 2023December 17, 2023 By thecodepathshala 1 Comment on C program check whether a number is even or odd
Write a C program to check whether a number is even or odd using if else.
Example:
Input : 
  Input number: 10
Output:
  10 is even number
/**
 * C program to check even or odd number
 */

#include <stdio.h>

int main()
{
    int num;

    /* Input number from user */
    printf("Enter any number to check even or odd: ");
    scanf("%d", &num);
    
    /* Check if the number is divisible by 2 then it is even */
    if(num % 2 == 0)
    {
        /* num % 2 is 0 */
        printf("Number is Even.");
    }
    else
    {
        /* num % 2 is 1 */
        printf("Number is Odd.");
    }

    return 0;
}

/*
Output :

Enter any number to check even or odd: 228
Number is Even.

Day – 2/Part – 2 : Operator and expressions

Posted on December 16, 2023December 16, 2023 By thecodepathshala No Comments on Day – 2/Part – 2 : Operator and expressions

An operator is a symbol that tells the compiler to perform a certain operation (arithmetic, comparison, etc.) using the values provided along with the operator. The values and variables used with operators are called operands. So we can say that the operators are the symbols that perform operations on operands. For example : Type of Operators Unary Operators :…

Day-2 / Part – 1 : Basic Input and Output in C

Posted on December 16, 2023December 16, 2023 By thecodepathshala 1 Comment on Day-2 / Part – 1 : Basic Input and Output in C

C programming language has standard libraries that allows us to take the input from a file or a keyboard and give the output to the screen or a file. Standard input (stdin) is used for taking input. Standard output (stdout) is used for giving output. Standard error (stderr) is used for giving error. The functions used for standard input and output…
