# C++ Exercises: Convert temperature in Celsius to Fahrenheit

## C++ Basic: Exercise-20 with Solution

Write a C++ program to convert temperature in Celsius to Fahrenheit.

Pictorial Presentation:

Sample Solution:

C++ Code :

``````#include <iostream>
using namespace std;

int main()
{
float frh, cel;
cout << "\n\n Convert temperature in Celsius to Fahrenheit :\n";
cout << "---------------------------------------------------\n";
cout << " Input the temperature in Celsius : ";
cin >> cel;
frh = (cel * 9.0) / 5.0 + 32;
cout << " The temperature in Celsius    : " << cel << endl;
cout << " The temperature in Fahrenheit : " << frh << endl;
cout << endl;
return 0;
}
``````

Sample Output:

``` Convert temperature in Celsius to Fahrenheit :
---------------------------------------------------
Input the temperature in Celsius : 35
The temperature in Celsius    : 35
The temperature in Fahrenheit : 95
```

## 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.
