Comparing int and uint with values above max leads to integral promotion
Check data type min and max
#include <stdio.h>
#include <limits.h>
int main(void)
{
printf("CHAR_MAX: %i\n", CHAR_MAX);
printf("UCHAR_MAX: %i\n", UCHAR_MAX);
printf("SHORT_MAX: %i\n", SHRT_MAX);
printf("USHORT_MAX: %i\n", USHRT_MAX);
printf("INT_MAX: %i\n", INT_MAX);
printf("UINT_MAX: %u\n", UINT_MAX);
return 0;
}
2147483647 and 1. c is negative and leads to the shell int a,b,c;
if(a >=0 && b >=0)
if(c >= 0){
printf("\n[*] ADDING %d + %d",a,b);
printf("\n[*] RESULT: %d\n",c);
}
else{
system("/bin/sh");
}
else
printf("nope");
