SIMPLE PROGRAM TO TEST POINTERS

Can someone explain to me why the buff in main doesn't contain the data/contents that I put inside of buff2

#include

#include

#include

int puff(int x, char *buff2) {

char contents[7] = {'c','d','e','j','a','z'};

x = 7;

buff2 = (char *)malloc(7);

memcpy(buff2, contents, 6);

puts("buff2");

if (buff2 != NULL){

for(int i=0; i

printf("%c ",buff2[i]);

}

}

return x;

}

int main()

{

puts("Hello World");

int num = 2;

char *buff = (char *)malloc(7);

int ret =0;

ret = puff(num, buff);

puts("");

puts("buff in main");

if (buff != NULL){

for(int i=0; i

printf("%c ",buff[i]);

}

}

puts("done");

return 0;

}
