for loops
for (initialization expr; test expr; update expr)
{
// body of the loop
// statements we want to execute
}
**Initialization Expression: In this expression we have to initialize the loop counter to some value. for example: int i=1;
Test Expression: In this expression we have to test the condition. If the condition evaluates to true then we will execute the body of loop and go to update expression otherwise we will exit from the for loop. For example: i <= 10;
Update Expression: After executing loop body this expression increments/decrements the loop variable by some value. for example: i++;**
