Summary C++ for, While, Do-While Loops

ELITE TUTORING




C++ for Loop
In computer programming, loops are used to repeat a block of code.

For example, let's say we want to show a message 100 times. Then instead of
writing the print statement 100 times, we can use a loop.

That was just a simple example; we can achieve much more efficiency and
sophistication in our programs by making effective use of loops.

There are 3 types of loops in C++.

• for loop
• while loop
• do...while loop




C++ for loop
The syntax of for-loop is:

for (initialization; condition; update) {
// body of-loop
}


Here,

• initialization - initializes variables and is executed only once
• condition - if true , the body of for loop is executed
if false , the for loop is terminated

, ELITE TUTORING



• update - updates the value of initialized variables and again checks the
condition
