Never use assignment operator in place of equality operator in the test
condition as it may cause an infinite loop.
Variable Declaration Inside Loop
C++ allows you to declare and initialize a variable inside the for loop. For example,
for (int i = 1, j = 5; i <= 10; i++)
In the preceding line, two variables i and j are declared and initialized inside the for loop.
Program 3: To display the table of 5.
#include<iostream.h> Output:
#include<conio.h> 5 * 1 = 5
void main() 5 * 2 = 10
{ 5 * 3 = 15
for (int i = 1, j = 5; i <= 10; i++) 5 * 4 = 20
cout << j << “ * “ << i << “ = “ << j * i << “\n”; 5 * 5 = 25
getch(); 5 * 6 = 30
} 5 * 7 = 35
5 * 8 = 40
Tech 5 * 9 = 45
5 * 10 = 50

If you want to execute just one statement in the body of the while loop,
you do not have to enclose the statement in braces.
THE WHILE LOOP
The while loop executes a set of statements repeatedly until a certain condition is met. The
syntax of the while loop is:
while (condition)
{
statements;
}
The while loop can accept expression and not just conditions, the following are all legal
expression:
