#include <vector>

intの場合

std::vector<int> nums;
nums.push_back(1);
nums.push_back(10);
nums.push_back(100);
nums.push_back(1000);
int cnt = nums.size();
log("num=%d", nums[0]); // 1
log("num=%d", nums[1]); // 10
log("num=%d", nums[2]); // 100
log("num=%d", nums[3]); // 1000
log("size=%d", cnt); // 4

charの場合

std::vector<char*> names;
names.push_back("taro");
names.push_back("jiro");
names.push_back("saburo");
int namecnt=names.size();
log("name=%s", names[0]); // taro
log("name=%s", names[1]); // jiro
log("name=%s", names[2]); // saburo
log("size=%d", namecnt); // 3
