$ echo -n '記号' | od -x 0000000 a8e8 e598 b78f
とすると,マルチバイト文字ごとに,バイトの連なりが逆になってしまう. そこで次のように処理する.
$ echo -n '記号' | hexdump -C 00000000 e8 a8 98 e5 8f b7
#include<iostream> #include <string.h> using namespace std; void test(char * input){ cout << input << endl; } int main() { char input[5120]; strcpy(input , "これはテスト"); test(input); return 0; }
#include <map> #include <vector> #include<iostream> using namespace std; void setText(vector<string> &v, map <string, int> &m1, map<string, int>::iterator & pa){ cout << "v.size = " << v.size(); pa = m1.begin();// for(int i = 0; i < v.size(); i++){ // pa = m1.find(v[i]); if( (pa = m1.find(v[i])) != m1.end()){ // if( (m1.find(v[i]))->second > 0){ //すでにマップにあるのなら cout << "find" << endl; pa->second = pa->second + 1; // (m1.find(v[i]))->second = ( (m1.find(v[i]))->second) + 1; //二つ目の数値を加算 } else{// そうでないなら,データを挿入 // pa.first = v[i]; // pa.second = 1; m1.insert(make_pair(v[i], 1)); // cout << "find " << endl; } }// end_for } int main() { vector<string> v; map<string, int> m1; map<string, int>::iterator pa; v.push_back("加藤"); v.push_back("鈴木"); v.push_back("佐藤"); v.push_back("山田"); setText(v,m1,pa ); pa = m1.begin(); int n = (int)m1.size(); for(int i = 0; i < n; i++){ cout << pa->first << " " << pa->second << endl; pa++; } return 0; }

#include <map> #include <vector> #include<iostream> using namespace std; void setText(vector<string> &v, map <string, int> & m1, map <string, int> & m2, int z, map<string, int>::iterator & pa, map<string, int>::iterator & pa2 ){ cout << "v.size = " << v.size(); for(int i = 0; i < v.size(); i++){ if( (pa = m1.find(v[i])) != m1.end()){ cout << "find in ma1" << endl; pa->second = pa->second + 1; } else{ // そうでないなら,データを挿入 // pa.first = v[i]; // pa.second = 1; m1.insert(make_pair(v[i], 1)); // cout << "find " << endl; } // pa = m1.find(v[i]); if( (pa2 = m2.find(v[i])) != m2.end()){ cout << "find in ma2" << endl; pa2->second = pa2->second + 1; // (m1.find(v[i]))->second = ( (m1.find(v[i]))->second) + 1; //二つ目の数値を加算 } else{ // そうでないなら,データを挿入 m2.insert(make_pair(v[i], 1)); } }// end_for } int main() { int i = 0; int j = 0; vector<string> v; map<string, int> m1,m2[2]; map<string, int>::iterator pa, pa2; v.push_back("加藤"); v.push_back("鈴木"); v.push_back("佐藤"); v.push_back("山田"); for(i =0; i < 2; i++){ pa = m1.begin(); pa2 = m2[i].begin(); // setText(v, m1, m2, i, pa, pa2); setText(v, m1, m2[i], i, pa, pa2); } int n = (int)m1.size(); pa = m1.begin(); for(i = 0; i < n; i++){ cout << pa->first << " " << pa->second << endl; pa++; } cout << "next" << endl; for(i = 0; i < 2; i++){ cout << "i = " << i << endl; pa2 = m2[i].begin(); for(j = 0; j < n; j++){ cout << " j = " << j << endl; cout << " " <<pa2->first << " " << pa2->second << endl; pa2++; } } return 0; }
よく忘れてはまる.pa は map <string,int> ma のイテレーターとする
printf("word = %s: freq = %d\n", (pa->first).c_str(), pa->second );

"__declspec(dllimport)" and "extern __declspec(dllexport)" both imply a declaration, but that "__declspec(dllimport)" causes the linker to look for the __imp symbol in an import library, while "extern __declspec(dllexport)" declares a function that must be defined in the program's source (no __imp prefix).
