QUESTION

Mia in a Tech competition was assigned a task for writing a function to determine how closely two words resemble each other. \n\nHow will Mia do this task?\n\nExample, the words \”TICK\” and \”TOCK\” have a score of 3, since three characters (T, C, K) are the same.\n\nSimilarly, \”CAT\” and \”DOG\” score 0, since no letters match.\n\nYou are given Strings A and B and you have to return an integer K indicating the score (as defined above) of how closely the two match.\n\nInput :\n\nFirst line of input contains an integer T denoting the number of test cases. Each test case contains two lines of input, where first line contains the string A and second line contains the string B.\n\nOutput :\n\nFor each test case print the score on a line.\n\nConstraints :\n\nA and B will each contain between 1 and 500 characters, inclusive.\nEach character of a and b will be ‘A’-‘Z’.\n1 <= T <= 50.

ANSWER

#include <stdio.h>
#include<string.h>
 
int main(void) {
 int t,i,a,b,c;
 char str[10000],str2[10000];
 scanf("%d",&t);
 while(t--)
 {
  c=0;
  scanf("%s",str);
  scanf("%s",str2);
  a = strlen(str);
  b = strlen(str2);
  if(a>=b)
  {
   for(i=0;i<b;i++)
   {
    if(str[i]==str2[i])
    c++;
   }
  }
  else if(a<b)
  {
   for(i=0;i<a;i++)
   {
    if(str[i]==str2[i])
    c++;
   }
   
  }
  printf("%d\n",c);
  for(i=0;i<b;i++)
  str2[i] = '\0';
 }
 return 0;
}
