6 7 The return Statement The return statement

6. 7 The return Statement • The return statement causes a function to end immediately. 1

Person 7 6. 7 Pernyataan kembali Ø Pernyataan kembali menyebabkan fungsi untuk segera mengakhiri.

Program 6 -11 // This program demonstrates a function with a return statement. #include <iostream. h> // Function prototype void halfway(void); void main(void) { cout << "In main, calling halfway. . . n"; halfway(); cout << "Now back in main. n"; } 3

Program 6 -11 / / Program ini menunjukkan fungsi dengan pernyataan kembali. #include <iostream. h> • / / Fungsi prototipe void halfway(void); void main(void) { cout << "In main, calling halfway. . . n"; halfway(); cout << "Now back in main. n"; }

Program continues //***************************** // Definition of function halfway. * // This function has a return statement that forces it to * // terminate before the last statement is executed. * //***************************** void halfway(void) { cout << "In halfway now. n"; return; cout <<"Will you ever see this message? n"; } 5

Program Lanjutan / / ************************ / / Definisi fungsi di tengah jalan. * / / Fungsi ini memiliki pernyataan return yang memaksanya untuk * / / Mengakhiri sebelum pernyataan terakhir dijalankan. * / / ************************ void halfway(void) { cout << "In halfway now. n"; return; cout <<"Will you ever see this message? n"; }

Program Output In main, calling halfway. . . In halfway now. Now back in main. 7

Keluaran Program Dalam utama, memanggil setengah. . . Dalam setengah sekarang. Sekarang kembali utama.

Program 6 -12 // This program uses a function to perform division. If division // by zero is detected, the function returns. #include <iostream. h> // Function prototype. void divide(float, float); void main(void) { float num 1, num 2; cout << "Enter two numbers and I will divide the firstn"; cout << "number by the second number: "; cin >> num 1 >> num 2; divide(num 1, num 2); } 9

Program 6 -12 / / Program ini menggunakan fungsi untuk melakukan pembagian. Jika pembelahan / / Dengan nol terdeteksi, fungsi kembali. #include <iostream. h> / / Fungsi prototipe void divide(float, float); void main(void) { float num 1, num 2; cout << "Enter two numbers and I will divide the firstn"; cout << "number by the second number: "; cin >> num 1 >> num 2; divide(num 1, num 2); }

Program continues //******************************** // Definition of function divide. * // Uses two parameters: arg 1 and arg 2. The function divides arg 1 * // by arg 2 and shows the result. If arg 2 is zero, however, the * // function returns. * //******************************** void divide(float arg 1, float arg 2) { if (arg 2 == 0. 0) { cout << "Sorry, I cannot divide by zero. n"; return; } cout << "The quotient is " << (arg 1 / arg 2) << endl; } 11

• Program Lanjutan / / ************************ / / Definisi fungsi membagi. * / / Menggunakan dua parameter: arg 1 arg 2 dan. Fungsi membagi arg 1 * / / Oleh arg 2 dan menunjukkan hasilnya. Jika arg 2 adalah nol, namun, file * / / Fungsi kembali. * / / ************************ void divide(float arg 1, float arg 2) { if (arg 2 == 0. 0) { cout << "Sorry, I cannot divide by zero. n"; return; } cout << "The quotient is " << (arg 1 / arg 2) << endl; }

Program Output with Example Input Enter two numbers and I will divide the first number by the second number: 12 0 [Enter] Sorry, I cannot divide by zero. 13

Program Output dengan Contoh input Masukkan dua angka dan saya akan membagi pertama nomor dengan jumlah kedua: 12 0 [Enter] Maaf, saya tidak bisa dibagi dengan nol.
