void test01() { string str1 = "我"; str1 += "爱XX"; cout << "str=" << str1 << endl; str1+='c'; string str2="LOL"; str1+=str2; } in 5、string查找替换 void test01() { string str1 = "adcdef"; int pos = str1.find("de");//从0开始 所以pos=3 //rfind pos...
1. 插入排序: 先用tmp=a[j+1]保存待插入的数,在还没有找到插入点时,直接用a[j+1] = a[j],免去每一次都交换;再插入数据后就可以跳出内部循环了。代码:public class InsertSort { public static void main(String[] args) { in java多个insert语句拼接 ...
std::map<int, std::string> ma {{1, "apple"}, {5, "pear"}, {10, "banana"}}; std::map<int, std::string> mb {{2, "zorro"}, {4, "batman"}, {5, "X"}, {8, "alpaca"}}; std::map<int, std::string> u; u.merge(ma); std::cout << "ma.size(): " << ma.size...
The std::map::insert() function is built in function in C++ STL and used for inserting the elements in map. We can use this function in following ways:insert(pair): to insert a pair in map. insert(pos, pair): to insert a pair at specified position in a map. insert(beg, end): ...
insert( ++c1.begin( ), c2.begin( ),--c2.end( ) ); cout << "[ c1 = "; for ( Iter = c1.begin( ); Iter != c1.end( ); Iter++ ) cout << *Iter << " "; cout << "]" << endl; // initialize a deque of strings by moving deque < string > c3; string str("a")...
Inserts elements at the specified location in the container. 1)Inserts a copy ofvaluebeforepos. 2)Insertsvaluebeforepos, possibly using move semantics. 3)Insertscountcopies of thevaluebeforepos. 4)Inserts elements from range[first,last)beforepos. ...
C++ STL set::insert() function: Here, we are going to learn about the insert() function of set in C++ STL (Standard Template Library).
Inserts elements at the specified location in the container. 1,2)Insertsvaluebeforepos. 3)Insertscountcopies of thevaluebeforepos. 4)Inserts elements from range[first,last)beforepos. This overload has the same effect as overload(3)ifInputItis an integral type. ...

a Number: "; cin >> theString; if (theString == "q") break; // extract each digit from the string, find its corresponding // entry in the map (the word equivalent) and print it for (index = 0; index < theString.length(); index++) { theIterator = theMap.find(theString[...
