Source Code to String Palindrome Program in C With Explanation. Write a program to check whether a string is a palindrome or not. First, we have to know what is palindrome String?. Palindrome is a word, phrase, or sequence that reads the same backwards as forwards, e.g. madam civic, radar, level and rotor.

We can do this by putting the condition if string[start++] is equal to string[ends--] then the string is a palindrome or if this condition fails then the string is not a palindrome. One more thing I want to clarify Palindrome may not only word, Palindrome may be a sentence.

		scanf("%s", string1);

		length = strlen(string1);

		for (i = 0; i < length; i++)
			if (string1[i] != string1[length - i - 1])
				flag = 1;
