C++ examples for Data Type:Array
Use arrays by reading a sequence of integers and then displaying them and their sum
#include <cstdio> #include <cstdlib> #include <iostream> using namespace std; int readArray(int integerArray[], int maxNumElements); int sumArray(int integerArray[], int numElements); void displayArray(int integerArray[], int numElements); int main(int nNumberofArgs, char* pszArgs[]) { cout << "Terminate the loop by entering " << "a negative number\n"; cout << endl;// www.j a v a2s. com int inputValues[128]; int numberOfValues = readArray(inputValues, 128); displayArray(inputValues, numberOfValues); cout << "The sum is " << sumArray(inputValues, numberOfValues) << endl; return 0; } int readArray(int integerArray[], int maxNumElements) { int numberOfValues; for(numberOfValues = 0;numberOfValues < maxNumElements;numberOfValues++){ int integerValue; cout << "Enter next number: "; cin >> integerValue; if (integerValue < 0){ break; } integerArray[numberOfValues] = integerValue; } return numberOfValues; } void displayArray(int integerArray[], int numElements){ cout << "The value of the array is:" << endl; for (int i = 0; i < numElements; i++){ cout << i << ": " << integerArray[i] << endl; } cout << endl; } int sumArray(int integerArray[], int numElements){ int accumulator = 0; for (int i = 0; i < numElements; i++){ accumulator += integerArray[i]; } return accumulator; }
