Reverse each word in string using pointers


Write a C Program to Reverse each word in string using pointers. Here’s simple Program to Reverse each word in string using pointers in C Programming Language.


What are Pointers?


A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

The general form of a pointer variable declaration is

  • type *var-name;

Here, type is the pointer’s base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer.

The unary or monadic operator & gives the “address of a variable’”.

The indirection or dereference operator * gives the “contents of an object pointed to by a pointer”.


Below is the source code for C Program to Reverse each word in string using pointers which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/* C Program to Reverse each word in string using pointers */

#include <stdio.h>
#include <conio.h>

int main()
{
        char str[50];
        int len,i,j,sp=0,start,end;
        char *s;

        printf("Enter any String :: ");
        gets(str);

        s=str;

    printf("\nAfter reversing Each Word of String [ %s ] :: \n",s);

        len=strlen(s);
        end=len-1;
        for(i=len-1;i>=0;i--)
        {
                if(s[i]==32 || i==0)
                {
                        if(i==0)
                                start=0;
                        else
                                start=i+1;
                        for(j=start;j<=end;j++)
                                printf("%c",s[j]);
                        end=i-1;
                        printf(" ");
                }
        }

        printf("\n");

        return 0;
}

Output : :


/* C Program to Reverse each word in string using pointers */
