我正在尝试在字符串数组(Alpha)的行中打印X(x =用户输入)数字,如果该行中有“ A”,则应在该行中打印一些内容(字符串或随机数),例如“这行有“ A”“。我无法弄清楚代码中有什么问题,例如代码中的这一行无法正常工作: (Alpha [dist(gen)] == Alpha [0])
它正在打印具有其他字符串字母(S,P C等)的行中的(“此行具有” A”)
#include <climits>
#include <ctime>
#include <fstream>
#include <iostream>
#include <random>
#include <string>
using namespace std;
int main() {
int num;
const int SIZE = 6;
cout << "How many iterations: ";
cin >> num;
string Aplha[SIZE] = {"A", "D", "P", "E", "C", "S"};
random_device randNum;
mt19937 gen(randNum());
uniform_int_distribution<> dist(0, 5);
uniform_int_distribution<> distRange(INT_MIN, INT_MAX);
for(int i = 0; i < num; i++) {
cout << Alpha[dist(gen)];
if(Alpha[dist(gen)] == Alpha[0]) {
cout << " this line has A " << distRange(gen);
}
cout << endl;
}
return 0;
}
结果应该是...
A this line has A 123231315
D
P
D
S
A this line has A 845421541
C
我得到的结果是这样的...
How many iterations: 10
S
S this line has A 1950029843
S
C this line has A -145672138
A
C
D
C
E
S

function getJarak(rWP1,rWP2){
return new Promise(function(resolve,reject){
var myRoute = L.routing.mapbox('thismyapi');
myRoute.route([rWP1, rWP2], function(err, routes) {
distance = routes[0].summary.totalDistance / 1000;
resolve(distance);
});
});
与检查function tampilTabelJarak(i,nama_kecamatan,distance){
var html;
var nomor = i;
html += '<tr>'+
'<td>'+nomor+'</td>'+
'<td>'+nama_kecamatan+'</td>'+
'<td>'+distance+'</td>'
'</tr>';
$('.data').html(html);
的{{1}}不同。每次致电Alpha[dist(gen)]
都会产生一个不同的随机数。

错误在接下来的两行中。每次调用Alpha[dist(gen)]
时,都会得到不同的索引。
Alpha[0]
我认为应该像波纹管一样。
dist(gen)
