There is a problem in this code check and solve this problem

Code:

#include<iostream.h> #include<conio.h> #include<stdlib.h> class bingo { public:int a[5][5]; void input(); void check(); void play(); void comp(); }; void bingo::input()//input a 5*5 matrix { int i,j,num; cout<<"\n Enter numbers 1-25\n"; for(i=0;i<5;i++) { for(j=0;j<5;j++) { cin>>a[i][j]; } endl; } } void bingo::check()//no number 1-25 must be repeated { int error=0; for(int i=0;i<5;i++) { for(int j=0;j<5;j++) { int num=a[i][j]; if(num==a[i][j+1]) { error=1; } } } if(error>0) { cout<<"\n Number repeated\n"; cout<<"PLEASE START OVER\n"; cout<<"\a"; getch(); exit(0); } } void bingo::play() { cout<<"\n START GAME\n"; for(int cal=1;cal<=25;cal++)//print input { for(int i=0;i<5;i++) { for(int j=0;j<5;j++) { cout<<a[i][j]<<" "; } cout<<"\n"<<"\n"; } cout<<"\n Enter the number to be striked\n"; int num,j,k=0,diag=0; cin>>num; for(i=0;i<5;i++)//place 0 in place of num { for(j=0;j<5;j++) { if(num==a[i][j]) { a[i][j]=0; if((a[k][k]==0)&&(diag!=5))//check for diagnol elements { diag++; k++; if(diag==5)//if all the 5 elents are 0 cout<<"\n Row completed\n"; } } } } } } void main() { clrscr(); bingo b; b.input(); b.check(); b.play(); }
