C Program to Search a String in the List of Strings

We’ll be working with two-dimensional strings in this program. The term “two-dimensional strings” refers to an array of strings. It’s comparable to a two-dimensional array, but it’s made up of strings.

We can read the string using gets(), fgets(), [n], and other methods. Following that, each string is compared to s1 (s1 is the string to search). If a string is discovered, strcmp() returns zero; otherwise, it returns non-zero. If we omit case sensitivity, then “Similar”, “similar”, and “SIMILAR” are all the same, and if you want to ignore case sensitivity in the program as well, you can use stricmp() or strcasecmp().

#include<stdio.h>
#include<string.h>
int main()
{
   char str[20][50], s1[50];
   int n, i, found=0;
   printf("Enter how many string (names): ");
   scanf("%d", &n);
   printf("Enter %d strings:\n", n);
   for(i=0; i<n; i++)
   {
     scanf("%s", str[i]);
   }
   printf("Enter a string to search: ");
   scanf("%s", s1);
   for(i=0; i<n; i++)
   {
     if(strcmp(s1, str[i]) == 0)
     {
       found=1;
       printf("Found in row-%d\n", i+1);
     }
   }
   if(found==0) printf("Not found");
   return 0;
}
