Your foo variable is declared as automatic storage and is local to the
getStr function.  As such, pointer you return will be valid, but the very
next instruction may very well overwrite this storage.
One way to solve it would be to declare foo as static (global) storage:

0001.00 #include <stdio.h>
0002.00 #include <string.h>
0003.00 #include <stdlib.h>
0004.00
0005.00 char foo[25];

0006.00 0007.00 char* getStr(int incomingVar)

0008.00 {

0009.00 sprintf(foo,"%d",incomingVar); 0010.00 return foo; 0011.00 }

Now the pointer you return will point to valid storage.
