A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.
In C++ we have three types of basic loops: for, while and do-while. In this tutorial we will learn how to use “for loop” in C++.
Syntax of for loop
for(initialization; condition ; increment/decrement)
{
C++ statement(s);
}
Flow of Execution of the for Loop
As a program executes, the interpreter always keeps track of which statement is about to be executed. We call this the control flow, or the flow of execution of the program.
