Loops

A for loop has the following syntax:

for(initial_value,condition,step){
  // code to execute inside loop
};

Here is a for loop example:

int cNum=0;

for (int i=1; i < 8; i++){
	cNum = cNum + i;
}

A while loop has the following form:

while(condition) {
	// code to execute
};

Let's see an example of while loop:

int cNum = 2;

while (cNum< 12){
	cerr << cNum<< endl;
	cNum += 2;
}

The output of the preceding program would be:

2
4
6
8
10
