IntSwap(int*,int*);LongSwap(long*,long*);StringSwap(char*,char*); 可采用宏定义TSWAP (t,x,y)或SWAP(x, y)交换两个整型或浮点参数: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #defineTSWAP(type,x,y)do{\ type _y=y;\ y=x;\ x=_y;\}while(0)#defineSWAP(x,y)do{\ x=...
char *s="GoldenGlobalView"; char *l="lob"; char *p; clrscr(); p=strstr(s,l); if(p) printf("%s",p); else printf("NotFound!"); get); return0; } //功能:从字串” string1 onexxx string2 oneyyy”中寻找”yyy” (假设xxx和yyy都是一个未知的字串) 1 2 3 4 5 6 7 char *s=...
*b=2; 指针要对应级别,一级b对应一级&a,二级c对应二级&b。 如果传值原代码块无星 main() { swap(a,b,c) } swap(int a,int *b,int **c) { a=*b+**c;//这样不能改变值 *b=a+**c;//可以改变值 } 函数里要改变原值只有指针 printf("%d",*b);//输出2 printf("%d",a);//输出2 ...
在C语言的宏中,#的功能是将其后面的宏参数进行字符串化操作(Stringfication),简单说就是将宏定义中的传入参数名转换成用一对双引号括起来参数名字符串。#只能用于有传入参数的宏定义中,且必须置于宏定义体中的参数名前。例如: 1 #define EXAMPLE(instr) printf("The input string is:\t%s\n", #instr) 2 ...

在指定行上下寻找错误点。你贴出的代码有很多乱码，可能是选择的文件编码错误导致的。错误的文件编码会导致编译失败。一般使用UTF8编码或GBK编码。define _CRT_SECURE_NO_DEPRECA TE 这里折行了，根据语义明显不该折行的，所以提示“TE”没有类型标识，改为 define _CRT_SECURE_NO_DEPRECATE 就好了 你...

if l == 0 { return "" } s, b := rawstring(l) memmove(unsafe.Pointer(&b[0]), unsafe.Pointer(p), uintptr(l)) return s } 3.3.2、更高效的字符串传递方法 C.CString 简单安全,但是它涉及了一次从 Go 到 C 空间的内存拷贝,对于长字符串而言这会是难以忽视的开销。
