Example of while loop using logical operator
C Programming Language / Loop control in C Language
30103Program:
#include <stdio.h> int main() { int i=1, j=1; while (i <= 4 || j <= 3) { printf("%d %d\n",i, j); i++; j++; } return 0; }
Output:
1 1 2 2 3 3 4 4 Press any key to continue . . .
Explanation:
Just like relational operators (<, >, >=, <=, ! =, ==), we can also use logical operators in while loop. The following scenarios are valid :
while(num1<=10 && num2<=10)
-using AND(&&) operator, which means both the conditions should be true.
while(num1<=10||num2<=10)
– OR(||) operator, this loop will run until both conditions return false.
while(num1!=num2 &&num1 <=num2)
– Here we are using two logical operators NOT (!) and AND(&&).
while(num1!=10 ||num2>=num1)
