How to ignore case in a search
You may have seen some other posts on the forum regarding a mileage chart.
I am trying to do a search and want the search to ignore the input letter case.
If I type in London, it finds London, however, if I type in london, it returns no result.
The project was finished and handed in, but it just bothers me that I did not get this to work.
Code:
// Cproject.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "string.h"
//Function Prototypes
int loc[10][10];
void distances(int[10][10],char [10][11]);
char towns[10][11];
void townSearch(char[10][11]);
void displayGrid();
void cost(int [10][10],char [10][11]);
int initialise();
char menu();
char option;
int match;
int arrayCount;
char input,rtn;
int arrayLocs[5];
int distance;
int totalCost;
int longDist;
/************************************************************************/

Anyone can show me would be much appreciated.
