Input the second number (num2).
Multiply num1 and num2, store the result in the variable result.
Display the result.
End
Pseudocode:
Start
Declare num1, num2, result as float
Input num1
Input num2
result = num1 * num2
Display result
How do you multiply two numbers in C?
The ‘*‘ operator can be used to add two numbers in C. Check below example
#include <stdio.h>
int main() {
int num1, num2, result;
// Input
printf("Enter the first number: ");
scanf("%d", &num1);
printf("Enter the second number: ");
scanf("%d", &num2);
// Multiplication
result = num1 * num2;
// Display Output
printf("The product of %d and %d == %d\n", num1, num2, result);
return 0;
}
Time complexity of the arithmetic operation (num1 * num2) is O(1) since it is a fundamental operation with a constant execution time.
More Examples on C Program For Multiplication Of Two Numbers
Example 1 : C Program to Multiply Two Floating-Point Numbers:
#include <stdio.h>
int main() {
float num1, num2, result;
// Input
printf("Enter the first number: ");
scanf("%f", &num1);
printf("Enter the second number: ");
scanf("%f", &num2);
// Multiplication
result = num1 * num2;
// Display Output
printf("The product of %.2f and %.2f == %.2f\n", num1, num2, result);
return 0;
}
The time complexity of the multiplication operation is O(1) for floating-point multiplication
Example 2 : C Program for Multiplication of Two Binary Numbers:
#include <stdio.h>
long long multiplyBinary(int binary1, int binary2) {
int i = 0, remainder = 0, sum[20];
long long binaryProduct = 0;
while (binary1 != 0 || binary2 != 0) {
sum[i++] = (binary1 % 10 + binary2 % 10 + remainder) % 2;
remainder = (binary1 % 10 + binary2 % 10 + remainder) / 2;
binary1 = binary1 / 10;
binary2 = binary2 / 10;
}
if (remainder != 0)
sum[i++] = remainder;
--i;
while (i >= 0)
binaryProduct = binaryProduct * 10 + sum[i--];
return binaryProduct;
}
int main() {
int binary1, binary2;
// Input binary numbers
printf("Enter the first binary number: ");
scanf("%d", &binary1);
printf("Enter the second binary number: ");
scanf("%d", &binary2);
// Multiply binary numbers
long long result = multiplyBinary(binary1, binary2);
// Display Output
printf("Product of %d and %d in binary: %lld\n", binary1, binary2, result);
return 0;
}
The amount of time needed to do binary multiplication is O(log(n)), where n denotes the maximum number of digits in the given binary numbers.
Example 3 : C Program for Multiplication of Two Numbers Using Functions
#include <stdio.h>
// Function to multiply two numbers
float multiply(float num1, float num2) {
return num1 * num2;
}
int main() {
float num1, num2;
// Input
printf("Enter the first number: ");
scanf("%f", &num1);
printf("Enter the second number: ");
scanf("%f", &num2);
// Multiplication using function
float result = multiply(num1, num2);
// Display Output
printf("The product of %.2f and %.2f == %.2f\n", num1, num2, result);
return 0;
}

Conclusion:
We covered the algorithm and provided pseudocode for a C program that multiply two integers in this article.
We implemented three separate programs: one that multiplied two floating-point numbers, one that multiplied two binary numbers, and one that used multiplication functions.
The guide also includes output and complexity analysis for a comprehensive understanding of the programs. These programs showcase the flexibility and versatility of C in handling different types of numbers and mathematical operations.
FAQ
How to multiply two numbers?
The ‘*’ operator in C can be used to multiply two numbers. For example, if you multiply num1 and num2, you get result = num1 * num2, which is then saved in the variable result.
What is the product of two numbers?
The product of two numbers is the result got by multiplying them together. In C programming, you can find the product of two numbers using the multiplication operator ‘*’.
How to add two numbers in C program example?
In a C program, the ‘+’ operator can be used to add two numbers. Here’s one example.
#include <stdio.h>
int main() {
    int num1, num2, sum;
    // Input
    printf(“Enter the first number: “);
    scanf(“%d”, &num1);
    printf(“Enter the second number: “);
    scanf(“%d”, &num2);
    // Addition
    sum = num1 + num2;
    // Output
    printf(“The sum of %d and %d == %d\n”, num1, num2, sum);
    return 0;
}
What is float in C programming?
‘float’ is a data type in C code that stands for floating-point numbers. It stores a real number (one with a decimal point). float num = 3.14; creates a float variable called “num” and assigns the value 3.14 to it.
What is the divide symbol in C?
The ‘/’ sign divides things in C. For division tasks between two numbers, it is used as the division operator. If you use result = num1 / num2;, it will divide num1 by num2 and keep the result in the variable result.
