By iterating through the characters in the string and counting them until it reaches the null character '\0', the function returns the length of the string as a size_t value. While strlen () is a useful tool for working with C ...
Nettet31. jan. 2024 · Basically, the Power function in C++ is responsible for calculating the power of any integer or variable. It is used to return the result of the first argument with respect to the power of the second argument. This function is defined in the cmath header file of Power function in C++.
