Write an assembly language version of the C library function strncpy(). As specified in the C library, the strncpy function should be a C callable function with the function prototype:

char *strncpy(char *st, char *ct, int n);

The function copies a string of n characters from ct to st, terminates it with the null terminator and returns the pointer st. The function assumes that the array st is large enough to contain n characters from array ct.

Note: Include the C stack frame in your assembly code.
