Loops in C Programming

Loops in C are used to change the sequence or flow of the program. The basic behavior of the program is that it starts it from the beginning of the program, executes the particular statement only once and proceeds to the next statement. This behavior is continued till the end of the program is reached. But sometimes we need to execute a particular statement more than once. At this point Loops in C plays an important role. Following are the types of Loops in C language we can use in the program: while loop do-while loop for loop statement
