Code to find the text in a given string. This is a word problem asked in many interviews.

Code

static void WordContainsInString()
 {
 int f = 0;
 Console.WriteLine("Input the string");
 string str = Console.ReadLine();
 Console.WriteLine("Input the word to search");
 string word = Console.ReadLine();
 int l = str.Length;
 int c = word.Length;

for (int i = 0; i < l; i++)
 {
 if (str[i] == word[0])
 {
 for (int K = i + 1, j = 1; j < c; j++, K++)
 {
 if (str[K] == word[j])
 {
 f++;
 }
 else { f = 0; }
 }
 }
 }
 if (f == c - 1)
 {
 Console.WriteLine("matching");
 }
 else
 {
 Console.WriteLine("not found");
 }
 Console.ReadLine();
 }

Call this method in main method.

static void Main(string[] args)
 {
 WordContainsInString();

}

Hope this helps you.
