使用char型数组保存数据,记得getchar()吸收换行符,其次在进行大小比较时记得将char型数据转换为整型。
#include <iostream> #include <cmath> #include <algorithm> #include <vector> using namespace std; char a[110][110]; bool flag[110] = {false}; int maxNum[110] = {-1}; int main(){ int n, m; cin >> n >> m; getchar(); for(int i = 0; i < n; ++i){ for(int j = 0; j < m; ++j){ cin >> a[i][j]; } getchar(); } for(int i = 0; i < m; ++i){ for(int j = 0; j < n; ++j){ if((a[j][i] - '0') > maxNum[i]) maxNum[i] = (a[j][i] - '0'); } } for(int i = 0; i < n; ++i){ for(int j = 0; j < m; ++j){ if(a[i][j] >= maxNum[j])flag[i] = true; } } int cnt = 0; for(int i = 0; i < n; ++i){ if(flag[i]) ++cnt; } cout << cnt; return 0; }
