【說明】
C++標(biāo)準(zhǔn)模板庫中提供了vector模板類,可作為動(dòng)態(tài)數(shù)組使用,并可容納任意數(shù)據(jù)類型,其所屬的命名空間為std。vector模板類的部分方法說明如下表所示:
【C++代碼】
#include <iostream>
#include <vector>
using namespace (1) ;
typedef vector< (2) > INTVECTOR;
const int ARRAY_SIZE = 6;
void ShowVector(INTVECTOR &theVector);
int main(){
INTVECTOR theVector;
// 初始化theVector,將theVector的元素依次設(shè)置為0至5
for (int cEachItem = 0; cEachItem < ARRAY_SIZE; cEachItem++)
theVector.push_back( (3) );
ShowVector(theVector); // 依次輸出theVector中的元素
theVector.erase(theVector.begin() + 3);
ShowVector(theVector);
}
void ShowVector(INTVECTOR &theVector) {
if (theVector.empty()) {
cout << "theVector is empty." << endl; return;
}
INTVECTOR::iterator (4) ;
for(theIterator = theVector.begin(); theIterator != theVector.end(); theIterator++){
cout << *theIterator;
if (theIterator != theVector.end()-1) cout << ", ";
}
cout << endl;
}
該程序運(yùn)行后的輸出結(jié)果為:(5)
