Introduction

An exercise in computer structure course, we were given a task to implement several methods similar to the string.h, as-

• char pstrlen(Pstring* pstr) - get the length of pstring
• Pstring* replaceChar(Pstring* pstr, char oldChar, char newChar) - replace all the oldChar with new char in pstring
• Pstring* pstrijcpy(Pstring* dst, Pstring* src, char i, char j) - copy src[i:j] to dst[i:j]
• Pstring* swapCase(Pstring* pstr) - replace every A to a, a to A and so on..
• int pstrijcmp(Pstring* pstr1, Pstring* pstr2, char i, char j) - compare between src[i:j] to dst[i:j]

main.s:

Getting an int from the user- length of the first "pstring" (n1), then getting n1 chars (without "\n") for the first pstirng. Than doing the same procces for the 2nd pstring. getting a number from the user (50-55) and run one of the functions above using switch case.
