Here we have used some basic inbuilt-functions of C program.

  • printf() – Used to print the string on the screen
  • & – Denotes the address of a variable. We will use this to store the value to the particular address of variable
  • scanf() – Used to take input from standard input
  • %d and %i are used to identifying the integer values.
  • %f are used to identify the float or fractional values
  • %c are used to identify the character values

Algorithm

In this algorithm, We will only take integer input and print that integer values only.

Step 1 : Start

Step 2: Declare integer variables as num1 and num2.

Step 3: Take input from the user and store it in num1 and num2

Step 4: Print num1 and num2

Step 5: End

Code to take input from user

#include<stdio.h>

int main()
{
    printf("\n\n\tLearn Programming with Codehelppro\n\n\n");

    int num1, num2;  
    float fraction;     
    char character;

    printf("Enter two numbers number : \n");
    
    // Taking integer as input from user
    scanf("%d%i", &num1, &num2);
    printf("\n\nThe two integer numbers that have entered : %d and %i\n\n", num1, num2);

    // Taking float or fraction as input from the user
    printf("\n\nEnter a Decimal number : \n");
    scanf("%f", &fraction); 
    printf("\n\nThe float or fraction number that you have entered : %f", fraction);

    // Taking Character as input from the user
    printf("\n\nEnter a Character : \n");
    scanf("%c", &character);
    printf("\n\nThe character that you have entered : %c", character);
    
    return 0;
}
