What is the difference between gets and Puts in C?

The main difference between gets and puts in C Language is that gets is a function that reads a string from standard input while puts is a function that prints a string to the standard output. C is a general purpose, high-level programming language. The definitions for these two functions are in header file.

What is the get function in C++?

How to use substring function in C?

You can use Substring method to find a substring between two strings. First, you need to find the position of the two strings in the string. Then use first string position as the starting position and find the length of the string by subtracting position of the first string from the position of the second string.
