Need Urgent help! Pass to a function

[macboyme]

Same Algorithm must be implemented within a function.
String is accepted in main() and passed to the function.

The code is about reversing each word in string.

code:
#include<conio.h>
#include<iostream>
#include<stdio.h>
using namespace std;

int main()
{
char a[30];
int i,j,k;
cout<<"Enter the string:" ;
gets(a) ;

for(i=0;a[i-1]!='\0';i++)
{
j=i;

while(a[j]!=' ' && a[j]!=NULL)
j++;
k=j;
while(j>=i)

cout<<("%a",a[j--]);
cout<<" ";
i=k;
}

void YourFunctionName(char a[])
{
// copy paste you algorithm here
}

int main()
{
char a[30];
int i,j,k;
cout<<"Enter the string:" ;
gets(a) ;
YourFunctionName(a);
}
