NPTEL Problem solving through Programming In C Week 11 All Programming Assignment Solutions | Swayam 2022. With the growth of Information and Communication Technology, there is a need to develop large and complex software.

ABOUT THE COURSE:

This course is aimed at enabling the students to:
  • Formulate simple algorithms for arithmetic and logical problems
  • Translate the algorithms to programs (in C language)
  • Test and execute the programs and  correct syntax and logical errors
  • Implement conditional branching, iteration and recursion
  • Decompose a problem into functions and synthesize a complete program using divide and conquer approach
  • Use arrays, pointers and structures to formulate algorithms and programs
  • Apply programming to solve matrix addition and multiplication problems and searching and sorting problems 
  • Apply programming to solve simple numerical method problems, namely rot finding of function, differentiation of function and simple integration

Program : 4  Write a C program to reverse a word using Recursion. Input to the program is a string that is to be taken from the user and output is reverse of the input word. Note that you have to use recursion.

				
					#include <stdio.h>
#define MAX 100
char *reverse(char[]);

int main()
{
    char str[MAX], *rev;
    //printf("Enter a String: ");
    scanf("%s", str);
    rev = reverse(str); //You have to write this function
    printf("The reversed string is : %s\n", rev);
    return 0;
}
char* reverse(char str[])
{
    static int i= 0;
    static char rev[MAX];
    if (*str)
    {
        reverse(str+1);
        rev[i++]= *str;
    }
    return rev;
}
