Mastering User Input with scanf() in C Programming

 Introducing scanf() in C Programming: Capturing User Input

What is scanf()?

scanf() stands as a powerful function for capturing user input from the standard input device, typically the keyboard.

The scanf routine, which accepts the response, has two arguments.

The first ("%i") specifies what type of data type is expected
The second argument (&number) specifies the variable into which the typed response will be placed.
Here & character means the address of

Syntax

int scanf(const char *format, ...);

Try this exercise yourself

Q : get two integer inputs from the user, calculates their sum, and then prints the result

#include <stdio.h> int main() { int num1, num2, sum; /*Prompt the user to enter two numbers*/ printf("Enter the first number: "); scanf("%d", &num1); printf("Enter the second number: "); scanf("%d", &num2); /* Calculate the sum of the two numbers*/ sum = num1 + num2; /* Print the sum*/ printf("The sum of %d and %d is: %d\n", num1, num2, sum); return 0; }
