Programs in C & C++ with Example

Counting words in a String using C: This is very good exercise to test new programmers pointer skills. The task is to count the words in a given string using C. Well there might be many ways you can do it, I will demonstrate mine way. Note that mine solution might not be the optimal one, but it gets the job done.

Operator overloading using friend functions: Operators can be overloaded in c++ with friend functions also. The procedure is same as we discussed earlier. Here I will demonstrate operator overloading with "+" operator which is a binary operator. I will be using a complex number class (called complex). The class will have 2 data types, real and imaginary. Operator overloading will not be a part of class complex, but we will declare that this function is a friend of class complex.
