For and while loops

These are the main loops I use when I code in any language, so I thought I make a guide on them in C++(works same way in C):

For loops: - These loops are pretty much that same as a while loop except you are able to set the incrementation and set the initial var value.
Loop example:

Code:

for(int x=1;x <= 10;x++) {
cout << x << "\n";
}

Explanation:
for(int x=1;x <= 10;x++) { - means that I am setting an integer variable with the value of 1. While x is less than or equal to 10, it will do what is defined within the braces. x++ increments x by 1 each time, the loop statement is true.

cout << x << "\n"; - That will output the value of x "\n" means go to a new line

} - That closes the loop

While loops: - This is basically does what is defined within the loop until the loop statement is no longer true

Loop Example:

Code:

int x = 1;
while(x <= 10) {
cout << x << "\n";
x++;
}

Loop Explanation:
int x = 1; - creates an integer named "x" with the value of 1

while(x <= 10) { - means while x is less than or equal to 10

cout << x << "\n"; - it will print the value of x along with the newline

x++; - increments x by 1 value

} - closes the loop
