if(Sqart) { ui->plainTextEdit->setPlainText(a=QString::number(x*x)); Sqart = false;

}This code snippet checks if the variable "Sqart" is true. If it is true, it sets the plain text of the "ui" object's plainTextEdit to the value of "a", which is set to the square of "x" converted to a QString using the "QString::number()" function. It then sets "Sqart" to false.

However, without knowing the context in which this code is being used, it's difficult to determine its overall purpose or functionality.

if(Add) { ui->plainTextEdit->setPlainText(a=QString::number(x+y)); Add = false; }以这种形式写出x²

if(Add) {
int x = 2;
int y = 3;
int result = x*x + y*y;
ui->plainTextEdit->setPlainText(a=QString::number(result));
Add = false;
}

这段代码将计算x² + y² 的结果，并将其显示在 plainTextEdit 中。其中，x 和 y 的值分别为 2 和 3，可以根据需要修改。

if(Add) { ui->plainTextEdit->setPlainText(a=QString::number(x+y)); Add = false; }以这种形式写出x²代码

if(Add) {
double x = 2.0;
double y = 3.0;
double result = pow(x, 2) + pow(y, 2);
ui->plainTextEdit->setPlainText(QString::number(result));
Add = false;
}
