Program 2 - CSU1128 - CSE 2026 - Shoolini University

Program to calculate sum after taking two numbers as input from user.

Explanation

The following code is written in C programming language and is a program that calculates the sum of two numbers entered by the user.

#include <stdio.h>

The first line includes the header file stdio.h, which stands for Standard Input/Output. This header file provides various functions that allow a program to input and output data, such as reading from the keyboard and writing to the console.

int main()

The main function is the entry point of the program, where execution starts. The int keyword before the main function indicates that the function will return an integer value.

float d, m, j;

The next line declares three floating-point variables d, m, and j.

printf("\n\n Program to calculate sum aftertaking two numbers as input from user. \n\n");

The printf function is used to print a message to the console that explains the purpose of the program.

printf("Enter 2 numbers - (Example: 2.34 5.66) and press enter: ");

The next line prints a prompt to the console, asking the user to enter two numbers.

scanf("%f %f", &d, &m);

The scanf function is used to read two floating-point numbers entered by the user. The %f format specifier is used to indicate that floating-point numbers are being read, and the & symbol before the variable names d and m is used to pass the addresses of the variables to the scanf function, allowing it to store the input values in those variables.

printf("Sum of the the entered numbers %.2f and %.2f is %.2f\n", d, m, d + m);

The printf function is used to print the sum of the two numbers, which is calculated as d + m. The %.2f format specifier is used to indicate that a floating-point number with two decimal places should be printed.

return 0;

The return 0; statement at the end of the main function indicates that the program executed successfully and returns an exit code of 0 to the operating system.
