A C program to input a string and output the reversed string using pointer notation

Let’s identify variables needed for this program. In this program, we need several variables to store string and count the number of characters in the given string. First variables will be the one which will save the string entered by the user and reverse of it. So it will be S[50] and R[50]. In C… Read More »
