#define SIZE (sizeof(array)/sizeof(int))
main()
{
if(-1<=SIZE) printf("1");
else printf("2");

program prints "2"
Here sizeof returns unsigned int value
so sizeof(array)/sizeof(int)
=> 32(unsigned int)/4(unsigned int)
=> 8 (unsigned int value)
During comparison, the datatypes are different on both sides of if condition
-1(signed int) <= 8(unsigned int)
so by rule of type conversion in c,
signed int gets converted to unsigned int
hence expression becomes
0xFFFFFFFF(unsigned int equivalent of -1) <= 8(unsigned int)
Hence overall condition becomes FALSE
