要求:比如1gjfg45 转换成：1GIFG45 #include int main() { char str[100] = "nishiw34odeyan4343"; char tar[100]; int index = 0; int pos = 0; //转换为大写 while(str[index] != '\0') { str[index] = (st

所有的参数传递都是值传递 #include typedef char *String; typedef String *STRING; void change1(String); void change2(STRING); int main() { char *name = "Hello world！"; puts(name); change1(name);

char *str = "what's your name?"; char src[] = "if you can think of anything, fake it"; 编译器会把src看作是数组元素的首地址，&src[0]的同义词。 注意：在数组形式中src是一个地址常量，不能更改，因为这意味着更改数组的存储的位置（地址）。 可以使用src+1来标识数组里的下一个元素。但不能用+

Defining Strings Within a Program As you probably noticed when you read Listing 11.1, there are many ways to define a string. The principal ways are using string constants, using char arrays, usi

char * a = "woyizhiza"; char b[10] = "woyizhiza"; 可以通过一个程序看一下：#include #include int main() { char *a = "woyizhiza"; char b[10] = "woyizhiza"; printf("%d\t%d\n", sizeof(a), strlen(a))
