Question

Write a C function that takes two strings (character arrays) as input and return 1 if they are equal and return 0 if they re not. Two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal in the same order.

Answer 1

#include<stdio.h>
int equalornot(char[],char[]);
int main()
{
char str1[100],str2[100];
printf("Enter a string1: ");
gets(str1);
printf("Enter a string2: ");
gets(str2);
int res;
res=equalornot(str1,str2);;
if(res==1)
printf("Strings are equal.");
else
printf("Strings are not equal.");
return 0;
}
int equalornot(char str1[], char str2[])
{
int i,len1=0,len2=0,count=0;
for(i=0;str1[i]!='\0';i++)
len1++;
for(i=0;str2[i]!='\0';i++)
len2++;
if(len1!=len2)
return 0;
else
{
for(i=0;str1[i]!='\0';i++)
{
if(str1[i]==str2[i])
count++;
}
if(count==len1)
return 1;
else
return 0;
}
}
