LISTING PROGRAM C++

Dibawah ini ada beberapa listing program dengan menggunakan bahasa pemrograman c++ dan Delphi. Semoga dapat menjadi refrensi bagi teman-teman yang membutuhkan untuk dipelajari atau untuk menyelesaikan tugas tertentu.

1. PROGRAM MENAMPILKAN DATA DALAM BENTUK MATRIK

//program menampilkan data dalam bentuk matrik
#include
#include
const long bar=3;
const long kol=3;
void main()
{
int i,j;
long matrik[bar][kol];
clrscr();
printf("Inputkan matrik A(3,3)\n");
for(i=0;ifor(j=0;j{
printf("A(%i,%)=",i+1,j+1);
scanf("%i",&matrik[i][j]);
}
printf("\nMatrik A(3,3) : ");
for (i=0;i{
printf("\n");
for(j=0;jprintf("%3i",matrik[i][j]);
}
getch();
}
2. MENCARI NILAI RATA-RATA

#include
#include
int main()
{
int nil[10];
double total,rata;
total=0;
printf("Inputkan data !\n");
for (int i=0;i<10;i++)
{
printf("data ke %i :",i+1);
scanf ("%d",&nil[i]);
total+=nil[i];
}
clrscr();
printf("Total dari : %i",nil[0]);
for(int n=0;n<9;n++)
printf("+%i",nil[n+1]);
rata=total/10;
printf("=%72f",total);
printf("\nNilai rata-ratanya : %72f,rata");
getch();
}
3. KONVERSI SUHU

//*========================*
//*===KONVERSI SUHU========*
//* *
//*contoh pemrosesan pada array,yaitu untuk penghitung nilai*
#include
#include
const int jum_data=5;
void main()
{
float suhu(jum_data);//aray suhu
float total; //untuk menampung total
clrscr(); //Hapus layar
cout <<"masukan data suhu "<for (int i=0; jum_data;i++)
{
cout<< i+1<< " : ";
cin>> suhu (i);
}
//menghitung nilai rata-rata
total=0;
for(i=0;icout <<"suhurata-rata ="<<
