C++ Exercises: Compute the specified expressions and print the output

C++ Basic: Exercise-35 with Solution

Write a program in C++ to compute the specified expressions and print the output.

Sample Solution:

C++ Code:

#include <iostream>
using namespace std;
 
int main()
{
    cout << "\n\n Compute the specified expressions and print the output:\n";
	cout << "------------------------------------------------------------\n";
    cout << " Result of the expression "<<"(25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) is : "<< (25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) <<"\n" ; 
}

Sample Output:

 Compute the specified expressions and print the output:              
------------------------------------------------------------          
 Result of the expression (25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) is : 2.13889

C++ Programming: Tips of the Day

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
