C语言 getmaxx()用法及代码示例


头文件graphics.h包含getmaxx()函数,该函数返回当前图形模式和驱动程序的最大X坐标。句法:

int getmaxx();

下面是getmaxx()函数的实现:

// C Implementation for getmaxx() 
#include <graphics.h> 
#include <stdio.h> 
  
// driver code 
int main() 
{ 
    // gm is Graphics mode which is 
    // a computer display mode that 
    // generates image using pixels. 
    // DETECT is a macro defined in 
    // "graphics.h" header file 
    int gd = DETECT, gm; 
    char arr[100]; 
  
    // initgraph initializes the 
    // graphics system by loading a 
    // graphics driver from disk 
    initgraph(&gd, &gm, ""); 
  
    // sprintf stands for “String print”. 
    // Instead of printing on console, it 
    // store output on char buffer which 
    // are specified in sprintf 
    sprintf(arr, "Maximum X coordinate for current "
        "graphics mode And driver = %d", getmaxx()); 
  
    // outtext function displays text at 
    // current position. 
    outtext(arr); 
  
    getch(); 
  
    // closegraph function closes the 
    // graphics mode and deallocates 
    // all memory allocated by 
    // graphics system .
