How do I use the while loop in C++.
So what the while loop does? we write the code once, and then it is going to run it forever or as many times we want to.
Creating a variable laurand with the value 1.
int laurand = 1;
Now the syntax of while loop is the while, and the inside the parthenses is the test of the code.
while(laurand <= 10)
It runs the code again and again.
cout << "It is doing the while loop" << laurand << endl;
The loop will keep running forever till the program crashes, otherwise if we want something like to tell while loop stop till to this number 10 and then add 1 number or more, example +1, +2, +5.
laurand = laurand +1;
The program will loop till reaches the 10, then it adds 1 more and stops at 11.
Watch live in action creating the program, or scroll below to copy the entire code.
Feel free to use the code.
