#include <stdio.h>void main(){ int A, B, T; scanf(“ %i ”, &A); scanf(“ %i ”, &B); T = A + B; printf(“ %i ”, T);}

Contoh program dalam Bahasa Cuntuk meng-input dua buah bilangan,menghitung dan mencetak totalnya

#include <iostream.h>void main(){ int A, B, T; cin >> A; cin >> B; T = A + B; cout << T;}

Turbo C C++

Program dan Bahasa Pemrograman C

----

void main() { statement statement statement statement }----

Beberapa contoh penempatan tanda kurung { dan }sebagai batas sebuah main program.

void main(){ statement statement statement statement

}

1.void main(){ statement statement statement

statement }

2.void main(){ statement statement statement statement

}

3.void main(){ statement statement statement

statement }

4.void main() { statement statement statement statement

}

5.void main() { statement statement statement

statement }

Struktur Bahasa C

#include <stdio.h>void main(){ int A, B, T; scanf(“ %i ”, &A); scanf(“ %i ”, &B); T = A + B; printf(“ %i ”, T);}

#include <iostream.h>void main(){ int A, B, T; cin >> A; cin >> B; T = A + B; cou << T;}

Turbo C C++

Perhatikan kata-kata (words) yang ada dalam kedua program tersebut, yaitu :

include stdio.hstream.h

main()scanf()printf()cincout

voidint
