Am I conatenating these strings correcting

[uscuba2]

My exposure to arrays and pointers are bit limited. And concatened strings even less ( it was not covered in my class so I had to use my book. ) So I know there are errors. I can not use any of C string libary functions. Thoughts?

#include <stdio.h>

char *strcat385(char string1[ ], char string2[ ]) {
int i = 0;

while(str[i])

{
string1[i] = str[i];
++i;
}

++i;

while(str2[])

{

string1[i] = strign2[];

++i;
}



string1 [i] = '\0';


}

int main( ) {
  char str[50] = "CSC course 385 ",
       str2[ ] = "sections 701, 710";
  printf("The return from strcat373:\n%s\n", strcat(str, str2));
  printf("string1 is %s\nstring2 is %s\n", str, str2);
}

while(str[i])

str hasn't been declared in that scope, same for str2.

Your function doesn't return a value, but it's supposed to return a char *.

printf("The return from strcat373:\n%s\n", strcat(str, str2));

The function you are writing is named strcat385()...

Main returns an int, try using

return 0;

at the end of the main function.
