String length in C String length C program to find length of a string, for example, length of the string “C programming” is 13 (space character is counted). The null character isn’t counted when calculating it. To find it, we can use strlen function of “string.h.” C program to find length of a string…

C program to reverse a string C program to reverse a string that a user inputs. If the string is “hello” then, the output is “olleh.” C program to reverse a string using strrev, without using strrev, recursion and pointers. A string which remains the same on reversal is a palindrome. Reverse a string…

C program to check subsequence C program to check Subsequence, don’t confuse subsequence with substring. In our program, we check if a string is a subsequence of another string. A user will input two strings, and we find if one of the strings is a subsequence of the other. Program prints yes if either…

C program to sort a string in alphabetic order C program to sort a string in alphabetic order: For example, if a user inputs a string “programming,” then the output will be “aggimmnoprr”, so output string will contain characters in alphabetical order. We assume input string contains only lower case alphabets. We count how…
