Thread: array of strings

Please try harder on the board before sending private requests for assistance! Ok?

Can you help me with something
How do I make this program more user
friendly..I want the USER to enter the names as oppossed to names already entered...


#include<iostream.h>
#include<string.h>
#include<stdio.h>
void SortApplicants( char*[]);
//SORTING STRINGS ARE HARD
main()
{
//I have to have the user enter the input
const int size = 80;
char sentence[size];
cin.getline( sentence, size);
//for ( int i = 0; i < 10; i++ )




SortApplicants(sentence);//Sort routine called
//ERROR BECAUSE???
return 0;
}


//********************************
void SortApplicants(char *alpha[])
{

char *temp;
int pass, k, row;

for(pass = 0; pass < 10; pass++)
{ for(k = pass; k >=1; k--)
{ if(strcmp(alpha[k], alpha[k-1]) > 0)
{ temp = alpha[k];
alpha[k] = alpha[k-1];
alpha[k-1] = temp;
}
}
}




for(row = 0; row < 5; row ++)
{ printf("%s", alpha[row]);
printf("\n");
}

return;}

//end program
