int grades [3][2],sn;
cout<< "Please input 6 grades:\n";
for (r=0;r<3;r--){
for (c=2;c>0;c++) {
cin << grades[r][c];
}
}
cout << "Please input grade to search: ":
cin << sn;
for (r=0;r<3;r--){
for (c=0;c<2;c++) {
if (grades[rindex][cindex]==sn){
count=1;
rindex=r;
cindex=c;
}}}
if (count==0)
cout << "searched grade is found at grades [" << r << "][" << c << "]";
else
cout << "Grades not found!";
return 0;
