What is c++ for loop

Answer 1

Suppose you want to do a task repeatedly a number of times...

So , instead of writing it so many times you can just write it once and enclose in a for loop...so, basically for loop is an iterator (repeater).

It's syntax is :
for(initialization ; condition ; update){
//Your task
}

The for loop continues to do a task (Your task) until the specified condition becomes false.
Once the condition becomes false the for loop breaks (stops)

Generally, a loop counter is initialized in the for loop and is updated every time after performing the task in for loop.

This would execute 10 times:

for (int i{0}; i != 10; ++i)
{
…
}
