# How to Multiply Two Integers in C

write a simple C program that can accept two integers from the user and calculate the product of the two integers.

If you are learning C programming, you might have encountered some problems that require you to perform some basic arithmetic operations, such as addition, subtraction, multiplication and division. For example, how do you multiply two integers in C? How do you store and display the result?

In this program, I will show you how to write a simple C program that can accept two integers from the user and calculate the product of the two integers. You will also learn some basic concepts of C programming, such as variables, data types, operators, input/output and comments.

What are the steps to multiply two integers in C?

To multiply two integers in C, we need to follow these steps:

• Declare three integer variables: a, b and product.
• Ask the user to enter the first integer and store it in the variable a.
• Ask the user to enter the second integer and store it in the variable b.
• Multiply the two integers using the * operator and store the result in the variable product.
• Print the result using the printf function.

#### C program

Now that we know the steps to multiply two integers in C, let's write the C program using these steps. Here is the complete code:

#include <stdio.h>

int main()

{

int a, b, product;

printf("Enter the first integer: ");

scanf("%d", &a);

printf("Enter the second integer: ");

scanf("%d", &b);

product = a * b; // calculate the product of the two integers

printf("The product of %d and %d is %d\n", a, b, product);

return 0;

}

#### Output

Enter the first integer: 5

Enter the second integer: 6

The product of 5 and 6 is 30

Enter the first integer: -3

Enter the second integer: 4

The product of -3 and 4 is -12

Enter the first integer: 0

Enter the second integer: 7

The product of 0 and 7 is 0

#### Conclusion

In this program, you learned how to write a C program that can accept two integers from the user and calculate their product. You also learned some basic concepts of C programming, such as variables, data types, operators, input/output and comments.
