An issue about 2D array in C

[xlttap]

char **sss;
sss = (char**)calloc(5,sizeof(char*));
for (int i = 0; i < 5; i++) {
sss[i] = (char*)calloc(256,sizeof(char));
strcpy(sss[i],"aaa");
}

sss = (char**)realloc(sss,3*sizeof(char*));
for (int i = 0; i < 3; i++) {
sss[i] = (char*)calloc(256,sizeof(char));
strcpy(sss[i],"aaa");
}

for (int i = 0; i < 8; i++) {
printf("sss = %s\n",sss[i]);
free(sss[i]);
}
free(sss);

Assue: It seems as if ''realloc" not works from the result printed.

I have been solved. haha

sss = (char**)realloc(sss,8*sizeof(char*));
for (int i = 0; i < 3; i++) {
sss[5+i] = (char*)calloc(256,sizeof(char));
strcpy(sss[5+i],"aaa");
}

It works OK! excellent. If the size realloced is less than the old size, the array
doesn't change any way.
