I have a program. Please tell me what do you think about this.

ERROR: failure to #include <stdio.h>


int main(int x)

ERROR: main can have two or no parameters. Not one. Usual is:

int main(int argc, char **argv)

{
if(x==1)
{
int myval;
printf("size of integer myval: %d\n",sizeof (myval));

ERROR: printf without a prototype.
ERROR: sizeof returns size_t, not int. Use
("%lu\n", (unsigned long) sizeof myval);

}
else
{
float myval;
printf("size of real myval: %d\n",sizeof (myval));

ERROR: printf without a prototype.
ERROR: sizeof returns size_t, not int. See above.

}

ERROR: main returns int. "return 0;" will do.

}

So, apart from not being a legal C program, all is well.
