hi i coded this pro...

#include <iostream.h>
#include <conio.h>
main(){
char q;
int y1,y2,p,o=0;
int m=0,d=0,g=0,s=0;
int chart1 [10][4];
int chart3 [10][4];
int G [10][4];
int M [10][4];
int S [10][4];
int D [10][4];
int temp[4];
for(int i=0;i<10;++i)
for(int j=0;j<4;++j){
G[i][j]=0;
M[i][j]=0;
S[i][j]=0;
D[i][j]=0;
}
char chart2 [10][23];

for(int i=0;i<=9;++i){
chart1[i][0]=(1+i);
}

for(int j=0;j<10;++j){
int sum=0;
cout<<"Enter the "<<(j+1)<<" player number:";
cin>>chart1[j][1];

cout<<"\nplease select the "<<(j+1)<<" player position(please ENTER IN CAPITAL FORM):";
cin>>q;
if(q=='G') chart1[j][3]='G';
if(q=='M') chart1[j][3]='M';
if(q=='S') chart1[j][3]='S';
if(q=='D') chart1[j][3]='D';
cout<<"\nplz enter the year1-year'1 of "<<(j+1)<<" player";
cout<<"\nhow many pair years do you want to enter?";
cin>>p;
for(int v=0;v<p;++v){>
cout<<"\nplz enter the year"<<(v+1)<<":";
cin>>y1;
cout<<"\nplz enter the year'"<<(v+1)<<":";
cin>>y2;
sum = sum +(y2-y1);
chart1[j][2]=sum;
}
}


for(int j=0;j<20;++j){
for(int i=0;i<10;++i){
if(chart1[i+1][2]>chart1[i][2]){
temp[0]=chart1[i][0];
temp[1]=chart1[i][1];
temp[2]=chart1[i][2];
temp[3]=chart1[i][3];
//---------------------
chart1[i][0]=chart1[i+1][0];
chart1[i][1]=chart1[i+1][1];
chart1[i][2]=chart1[i+1][2];
chart1[i][3]=chart1[i+1][3];
//----------------------
chart1[i+1][0]=temp[0];
chart1[i+1][1]=temp[1];

chart1[i+1][3]=temp[3];
//---------------------
} }}

for(int i=0;i<10;++i){//
cout<<"\n";//                  
for(int j=0;j<4;++j)//      
cout<<"  "<<chart1[i][j];//
}//

 cout<<"\n";

for(int i=0;i<10;++i){//
if(chart1[i][3]=='D'){//
for(int j=0;j<4;++j){//
D[o][j]=chart1[i][j];}//
++o;}}//                      
//
for(int i=0;i<10;++i){//
cout<<"\n";//
for(int j=0;j<4;++j)//
cout<<" "<<D[i][j];//
}//
///


getch();
}

before i add this part

for(int i=0;i<10;++i){//
if(chart1[i][3]=='D'){//
for(int j=0;j<4;++j){//
D[o][j]=chart1[i][j];}//
++o;}}//
//
for(int i=0;i<10;++i){//
cout<<"\n";//
for(int j=0;j<4;++j)//
cout<<" "<<D[i][j];//
}//
///

the output of chart1 is something like this:
6 1 7 71
5 20 4 83
8 24 4 68
10 80 4 77
7 23 3 68
9 17 3 68
2 8 2 68
3 14 2 83
4 16 2 77
1 9 1 68

but after adding those codes the output of chart1 is:

4239560 1638200 4207616 4263780
5 20 4 83
8 24 4 68
10 80 4 77
7 23 3 68
9 17 3 68
2 8 2 68
3 14 2 83
4 16 2 77


and also the input is:
1 9 1 D
2 8 2 D
3 14 2 S
4 16 2 M
5 20 4 S
6 1 7 G
7 23 3 D
8 24 4 D
9 17 3 M
10 80 4 D


WHY after adding that code the output change?
what should i do?
