C program to input and output a number and a character

Input and Output a number and a character:-

Today we will practice some of the c programming examples which will be very simple and easy to execute.

Installing code blocks for c and c++ in windows.

1. The first program, in this we are taking a character input from user and print that character on the screen. Refer the program below for understanding better.

   #include <stdio.h>

    int main()
    {   
        char ch;
        printf("Enter a character to be display: ");
        scanf("%c", &ch);
        printf("The character entered is: %c", ch);   
        return 0;
    }
    
    Output :
     Enter a character to be display: A  
     The character entered is: A  

2. The second program is similar to the first program where we take a character as input and prints it on the screen where as in this program we take the input as an integer and similarly prints that on the screen.

#include <stdio.h>

int main()
{   
    int num;
    printf("Enter a number to be display: ");
    scanf("%d", &num);
    printf("The number entered is: %d", num);   
    return 0;
}
output:-
Enter a number to be display: 12                                                                                      
The number entered is: 12  

3. This program is also similar to the to the programs one and two where we take the input and print on the screen. Here we are taking a float value and printing it.

#include <stdio.h>

int main()
{
    float value;
    printf("Enter value: ");
    scanf("%f", &value);
    printf("The value entered is: %f", value);

    return 0;
}

output:-
Enter value: 25                                                                                                       
The value entered is: 25.000000

4.The below program takes two inputs one is a character and other one is an integer value

First we input a character and then an integer in the below diagram. 

#include <stdio.h>
int main() 
{
   char ch;
   int n;
   printf("Enter a character") ;
   scanf("%c", &ch) ;
   printf("Enter an Integer value") ;
   scanf("%d", &n) ;
   printf("The entered character is %c and the entered integer is %d, ch, n) ;
   return 0;
}

Output:
Enter a character A
Enter an Integer value 2

The entered character is A and the entered integer is 2
