iii. Replace mmm with code that sets a equal to b with bit 5 set and bit 7 cleared

int myfunc(int b)
{
int a = 0;
if (b == 10)
xxxx // set bit 3 of a

Read the homework policy.

Then read the bitwise operator FAQ.

Hi Syscal


I have some doubts here.


To set bit3 of variable a,
I used this way

void set_bit3(void) // set bit 3 of a
{
a |= BIT3;
}


Is it correcT?

How about you write a small test program to find out? One that actually fully compiles and runs.
