Array display problem

Here is a program i have the the problem with it is that the array totalwin[5] via (totalwin[cnt]) is displaying some weird figures on the first display it also displays the correct figure on the final display but to 6 decimal places.


what am i doing wrong and how can i fix this ?

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

int main (void)

{ // Begin //
 	
 // Variables//
 int choice,result,play1=38000,play2=38000,pbet;
 int cnt = 0 , cnt2 =0 ;

 char fname[15],mname[15],lname[15],c;
 float amtwon,amtlost,totalwin[5],doublebet,avgwin,ovwin=
0;
 
 
 
 // User chooses their country's desgenation//
 printf("\n Enter 1 for first world country !\n");
 printf(" Enter 2 for second world country !\n");
 printf(" Enter 3 for thrid world country !\n");
 printf("\n Choose where you are from: ");
 scanf ( "%d",&choice);	

// This while loop ensures an error message will come up unless the right values are entered 	

while ( choice < 1 || choice >3)
	       { 
 	       printf(" Error please choose a number from the list above ");
           scanf("%d",&choice); 
		   }
