Write a C program to add Two Integers
A C program to add two integers is a fundamental example often used to introduce beginners to the basics of programming. This program demonstrates the basic structure of a C program and the use of variables and arithmetic operations.
Explanation:
- Include Header File: The #include <stdio.h> directive is used to include the standard input-output library, which is necessary for functions like printf and scanf.
- Main Function: The main() function is the entry point of every C program. The execution of the program starts from the main() function.
- Variables: Declare variables to store the two integers and the result of the addition.int num1, num2, sum;
4.Input: Use scanf to get input from the user for the two integers.
printf(“Enter the first integer: “); scanf(“%d”, &num1); printf(“Enter the second integer: “); scanf(“%d”, &num2);
5. Addition: Perform the addition operation.
sum = num1 + num2;
6.Output: Display the result using printf.
printf(“Sum: %d\n”, sum);
Add Two Integers User Input:
#include <stdio.h> int main(){ int mum1, mum2, Sum of integers; printf("Enter first integer: ");//entered by user// scanf("%d", &num1);//entered by user// printf("Enter second integer: "); scanf("%d", &nuum2); Sum of integers = num1 + num2;//using sum adding two integers// printf("Sum of %d and %d is %d", first integer, second integer, Sum of integers); return 0; }
Output:
Enter first integer: 2 Enter second integer: 4 Sum=6
Conclusion:
In conclusion, this simple C program serves as a foundation for understanding basic programming concepts such as variable declaration, user input, arithmetic operations, and output display. It provides a hands-on experience for beginners to grasp the structure and syntax of a C program. As you progress in your programming journey, you’ll encounter more complex tasks and concepts, building upon the foundational knowledge demonstrated in this introductory program.
