C - User Input

 C - User Input

To get user input in C language, use the scanf(). It is used to read the data input by the user on the console. Let us see an example C program to get input from the user.

C program to print an integer entered by the user

Let us see an example to enter an integer from the user using scanf() and display using printf():

#include <stdio.h> int main() { int i; # Asks the user to enter a number printf("Enter a number = "); scanf("%d",&i); # Displays the number entered by the user above printf("\nThe number entered by user = %d ",i); return 0; }

Output

Enter a number = 10 The number entered by user = 1

C program to print the multiplication of integers entered by the user

Let us see another example wherein we will get three numbers from the user and multiply them:

#include <stdio.h> int main() { int a, b, c; // Three numbers int res; // Asks the user to enter three numbers one-by-one printf("Enter the 1st number = "); scanf("%d",&a); printf("Enter the 2nd number = "); scanf("%d",&b); printf("Enter the 3rd number = "); scanf("%d",&c); // Multiply the numbers entered by the user res = a*b*c; printf("Multiplication Result = %d ",res); return 0; }

Output

Enter the 1st number = 5

Enter the 2nd number = 10

Enter the 3rd number = 15

Multiplication Result = 750
