I have a question...

Question

#include <stdio.h>

int main()
{
int a;
int b;
for (a=0, b=0; a<5, b<6; a++, b++)
{
printf("%d %d\n", a, b);
}
return 0;
}

/*The output is:
0 0
1 1
2 2
3 3
4 4
5 5
When the variables a and b are incremented to both be 5 by a++ and b++, it will check this condition: a<5, b<6. Why the program print "5 5" because the a<5 is not true? Although the b<6 is true, so both conditions must be false in order to get out of the loop?*/

Answer 1

Thx

Answer 2

Multiple conditions in for loops with a bit differently; in the for loop, everything but the last condition is "thrown away". So in this case the "a < 5" condition is discarded and only the "b < 6" condition is checked.
