Write a program to compare two strings?

Answer 1

Registers used: ax,ds,si,di,cl

flags affected: zf,cf

program:

assume cs:code,ds:data

code segment

mov ax,data

mov ds,ax

mov si,offset str1

mov di,offset str2

mov cl,count

cld

rep cmpsb

hlt

code ends

data segment

str1 db 04h,05h,07h,08h

count equ 04h

org 0010h

str2 db 04h,06h,07h,09h

data ends

end

result:

input: str1 (ds:0000h) = 04h,05h,07h,08h

str2 (ds:0010h) = 04h,06h,07h,09h

Answer 2

There are two different types of equality for Strings - object equality (==) and comparative (compareTo(), equals()). Object equality compares the memory addresses of two Strings, which is probably not what you are looking for. To test for equality, you can use String's equals() method.

Example: "abc".equals("abc"); //true

Answer 3

#include <stdio.h> #include <string.h> int main() { char *str1 = "sample", *str2 = "sample"; if(strcmp(str1,str2)==0) printf("strings are equal"); retrun 0; }

Answer 4

in java, two strings can be compared .but not by using the pointers because there is no existence of pointeres in java.
