Problem: Write a C++ program to accept four numbers from the user a, b, c, and d and compute the addition of (a/b) with (c/d). The formula to compute the addition of two fractions is given below (a*d + b*c)/(c*d). Print the final value as output on the screen.

Note: Do not write any C++ statements for printing general messages. For example, the following should NOT be present in your program:cout << "Enter a number:", cout << "The computed answer is", etc. In addition, do not print unnecessary spaces unless specified in the program. You just have to print the result.

Student submission:
#include<simplecpp>

	cin>>a>>b>>c>>d;
	if(a>=1	&&d<=100){
