C: Search a string within the array of strings

Question

Please help to write a function that searches for the unique part of a string in an array of strings.

Comments

You wanted to search a single string in a list of array of strings i.e
{"yes", "no", "hello", "world"} and you wanted to search "hello" i.e a single whole string,
or you wanted to search like "ll" or "es" (sub string inside a string) something like that.
please specify
Thanks

Wanted to search ll or es :)

Answer 1

Here is the program for the above (tested). Have a look.

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

int main()
{
    char str_arr[5][10] = {"Yes", "No", "hello", "world", "test"};
    char *str = "st", *tmp = NULL;
    int i = 0;

    // It will go through each string and will check for the sub-string.
    while(i < 5) {
        if ((tmp = strstr(str_arr[i], str))) {
            /*
               If you want to ignore the case of letters i.e capital or small letter then just replace
               strstr() with strcasestr();
            */
            break;
        }
        i++;
    }

    if (tmp) {
        printf("sub string [%s] is found in string [%s]\n", str, str_arr[i]);
    } else {
        printf("string not found\n");
    }

    return 0;
}

Answer 2

This example calls the IndexOf method on an array of strings to report the string number and index of the first occurrence of a substring. using C#

Example

string[] strArray = {"ABCDEFG", "HIJKLMNOP"};
string findThisString = "JKL";
int strNumber;
int strIndex = 0;
for (strNumber = 0; strNumber < strArray.Length; strNumber++)
{
    strIndex = strArray[strNumber].IndexOf(findThisString);
    if (strIndex >= 0)
        break;
}
Console.WriteLine("String number: {0}\nString index: {1}",
    strNumber, strIndex);

Compiling the Code

Copy the code and paste it into the Main method of a console application.

Note: here i am using Indexof method, please check this as a reference i will update the code C language as soon as possible
