Sorry to start a new thread, but does this work for setting a bit?

[knik653]

If I want to set the 31st bit of test_summary to the value of result, does this work? ( note: I simplified the code )


int test_summary = 0;

int result = 1;

test_summary = test_summary | result << 31;

#include<stdio.h>
int main( void )
{
    int test_summary = 0;
    int result = 1;
    test_summary = test_summary | result << 31;
    printf( "%d\n", test_summary );
    return 0;
}

What doesn't work?

I am asking if this correct syntax or not for setting the 31st bit of test_summary to the value of result?

Now I am thinking it should be:
test_summary = test_summary & result << 31;

????
I am on the right track?
