This function returns the product of these numbers. To understand this program you should have the knowledge of following C Programming concepts: #include <stdio.h> /* Creating a user defined function product that * multiplies the numbers that are passed as an argument * to this function. It returns the product of these numbers */ float product(float a, float b){ return a*b; } int main() { float number1, number2, prod; printf("Enter first Number: "); scanf("%f", &number1); printf("Enter second Number: "); scanf("%f", &number2); // Calling product function prod = product(number1, number2); // Displaying result up to 3 decimal places. printf("Product of entered numbers is:%.3f", prod); return 0; }
