Problem with Sorting a sorted array

[hiddenx]

Hi ,The problem with my code is Highlighted with Bold , I want to sort inside that else if , But after i choose the option in the introduction , the output window will freeze and execution will stop. Same for Displacement , How can i solve this problem. I tried many thing , Everything else works properly. If i put the sortlisting(); , in the start of main() , It works only for the CATEGORY order , but i want it to sort each thing when it gets into the else if of different options. The options are there in the intro Section of the program.

#include<iostream>
#include<fstream>
#include<string>
#include<sstream>
#include<stdio.h>

    string accel;
    string cyl;
    string cool;
    string ohc;
    string brake;
    string valve;
    string torque;
    string weight;
    string induct;

	{

            case 6:

			default:

	}
//Ending of Compare.
