Answer / binoy mathew
#include <iostream>
#include <stdlib.h>
#define max 100
#define max 200
int main()
{
printf("%d",max);
return 0;
}
save and run.
[root@localhost Desktop]# g++ test.cpp
test.cpp:5:1: warning: "max" redefined
test.cpp:4:1: warning: this is the location of the previous
definition
[root@localhost Desktop]# ./a.out
200
it shows a warning, but the value used is the latest.
