Answer 1

#include<stdio.h>
#include<string.h>
int min(int a,int b)
{
        if(a<b)
                return a;
        else
                return b;
}
main()
{
        char str1[50],str2[50];
        printf("Enter string 1 \n");
        scanf("%s",str1);
        printf("Enter string 2 \n");
        scanf("%s",str2);
        int length = min(strlen(str1),strlen(str2));
        char str3[length+1];
        int i=0,j=0;
        for(;i<length;i++)
        {
                if(str1[i]==str2[i])
                        str3[j++]=str1[i];
        }
        str3[j]='\0';
        printf("%s\n",str3);
}
