The most complete collection of love codes in the history of C language and C++, with color flashing, character filling, and source code attached

The first type: red love code Go directly to the code: #include<stdio.h> #include<Windows.h> int main() {<!– –> system(” color 0c”);//Design program color printf(“It is a very happy thing to meet you, I love you!!!\\ “);//Print text \t float x,y,a;//define variables x,y,a \t for(y=1.5f;y>-1;y-=0.1f) {<!– –> for(x=-1.5f;x<1.5f;x + =.05f){<!– –> a=x*x + y*y-1; putchar(a*a*a-x*x*y*y*y<0.0f?’x’:’ ‘); } […]

Filling the hole: Java’s String class (1)

Common methods String construction Let’s take a look at the String construction method in the source code Common string //”hello” is a string constant, without \0 mark at the end String str = “hello”; System.out.println(str);//hello String str2 = new String(); System.out.println(str2);//No output String str3 = new String(“pppp”); System.out.println(str3);//pppp String array char[] array = {‘a’,’b’,’c’}; String […]

Qt uses QAxObject to write to Excel tables for color filling, merging cells, multi-line writing, etc.

Qt uses QAxObject to write to Excel tables, including color filling, merging cells, multi-line writing, etc. QAxObject can call various functions or events in the Excel table to control reading and writing Excel tables. All interfaces in the Excel table can be viewed in the official documentation. Source code can be seen at the end. […]
