cout<<"Data Kampus"<>nim[i]; cout<<"Nama Mahasiswa : ";cin>>nm[i]; cout<<"Data Mahasiswa"<>kmk[i][j]; cout<<"Nama Mata Kuliah : ";cin>>nmk[i][j]; cout<<"SKS : ";cin>>sks[i][j]; cout<<"Nilai : ";cin>>nilai[i][j];

mutu[i][j]=sks[i][j]*nilai[i][j]; ssks=ssks+sks[i][j]; smutu=smutu+mutu[i][j]; } ip[i]=smutu/ssks; if(ip[ti]ip[i]){tr=i;} }

for(k=1;k<=3;k++){ cout<<"No : "<=3,50)){cout<<"Sangat Baik"<=2,75)){cout<<"Sangat Baik"<=2,00)){cout<<"Sangat Baik"<=0,00)){cout<<"Sangat Baik"<
