Program to check whether two string are equal or not

[seema_thk]

Hi Friends,

I have to write the program , in which I have to check whether two given string are equal or not. I have tried many techniques but not successful.

Please help me to code this program to compare two string.

Your help will greatly appreciated...

Hi all,

Please try to run the below program. Below code is running successfully on my machine and gives correct output i.e check the two string:

#include<stdio.h>
#include<conio.h>

int strngcmp(const char *a1, const char *a2)
{
unsigned int x = 0, diffrc;
while(*(a1+i) && *(a2+x))
{
diff = (*(a1+x)-*(a2+x));
if(!diffrc)i++;
else break;
}
return diffrc;
}
int main()
{
printf("chuma %d ", strngcmp("pqos","pqrst"));
return 0;
}

Why don't you try below program code to compare two string?

Program code:

#include <string.h>
#include <stdio.h>

void stringchk(char s1[], char s2[]);

int main()
{

char strg1[10],strg2[10];

printf("Enter 1st String:");
scanf("%s",strg1);

printf("Enter 2nd String:");
scanf("%s",strg2);

stringcmp(strg1,strg2);

return 0;
}

void stringchk(char *p1, char *p2)
{
int a,b;

for(a=0;s1[a]!='\0';a++)
{
for(b=0;p2[b]!='\0';b++)
{
if(p1[a] == p2[b])
continue;
}
}

if (a==b)
{
printf("String p1:%s and p2:%s are Equal\n",s1,s2);
}
else
printf("String p1:%s and p2:%s are Not Equal\n",s1,s2);

}

Hi friends,

I suggest you to use nested loop here. Refer the below program, I used "If" loop inside the "For" loop. And at the end I am checking the test condition using "if" loop, which check whether given two string are equal OR not

#include<conio.h>
#include<iostream.h>
#include<stdio.h>

void main()

{
clrscr();
int n=0;
char l[10];

char m[10];
gets(l);
gets(b);
for(int a=0,b=0;b[i]!='\0'||x[j]!='\0';a++,b++)
{
if(a[i]!=b[j])
{
l++;

}

}
if(n==0)
cout<<"Given strings are matching";
else
cout<<"string strings doesn't matching";

getch();
}
