for loop with multiple test conditions
C Programming Language / Loop control in C Language
3086Program:
#include <stdio.h> int main() { int i,j; for (i=1,j=1 ; i<3 || j<5; i++,j++) { printf("%d, %d\n",i ,j); } return 0; }
Output:
1, 1 2, 2 3, 3 4, 4 Press any key to continue . . .
Explanation:
Multiple initialization inside for Loop in C
We can have multiple initialization in the for loop as shown below.
for (i=1,j=1;i<10 && j<10; i++, j++)
What’s the difference between above for loop and a simple for loop?
1. It is initializing two variables. Note: both are separated by comma (,).
2. It has two test conditions joined together using AND (&&) logical operator. Note: You cannot use multiple test conditions separated by comma, you must use logical operator such as && or || to join conditions.
3. It has two variables in increment part. Note: Should be separated by comma.
