Example 3: Check the Empty String To Remove the First Character From the String in C++ Before using the string::erase function, ensure there isn’t an empty string. If the input sequence is empty, the program throws a std::length error exception. The program includes the main function wher...
#include<iostream>#include<string>using std::cin;using std::cout;using std::endl;using std::string;intmain(){string str=" Arbitrary str ing with lots of spaces to be removed .";cout<<str<<endl;str.erase(std::remove(str.begin(),str.end(),' '),str.end());cout<<str<<endl;retur...
The syntax belowyour_string.pop_back();operates on a string variable namedyour_string. It uses thepop_back()member function of thestd::stringclass to remove the last character from the string. Syntax: your_string.pop_back(); In this code example, we have a string variable namedstrto sto...
Similarly, we can also use thesubstr()function in C++ to remove the last character of a string like this. #include<iostream>#include<string.h>usingnamespacestd;intmain(){string user="Johnd";string result=user.substr(0,user.size()-1);cout<<result;return0;} ...

以下是一个简单的示例,使用erase-remove惯用法来删除所有空格: 代码语言:cpp 复制 #include<iostream> #include<algorithm> #include<string> int main() { std::string str = "Hello, World!"; str.erase(std::remove(str.begin(), str.end(), ' '), str.end()); std::cout<< str<< std::...
Here is the source code of C++ Program to Remove the Spaces in a String. The program output is shown below. #include<iostream> #include<string.h> usingnamespacestd; intmain() {charstr[80]; inti=0, len, j; cout<<"Enter a string : "; ...
QString &QString::remove(qsizetype position, qsizetype n) 作用:删除源字符串从position开始,包括position的后n个字符 如果position + n超出了原字符串的长度,则会把position后的字符全删掉;如果n<0则直接返回; 如果position<0,则会从字符串最后开始删除,最后一位算-1,以此类推; 注意:字符串中字符的删除不...
