Explanation of Solution

Program:

The following program will evaluate the given expression.

//include the header file

#include <stdio.h>

//definition of main method

int main (void)

{

//declare the variable

float ans;

//calculate the ans

ans = (3.31e-8f * 2.01e-7f) / (7.16e-6f + 2.01e-8f);

//display the result

printf ("The answer is %e\n", ans);

//return statement

return 0;

}

Explanation:

In the above program, declare the required header file. Inside the main method, declare the variable. Then calculate the “ans” value and print the result on the output screen.
