c - 设置一个指向char数组第n个地址的指针

嗨，我想设置一个指向数组第n个字符的指针：

// create pointer
char *originalPointer;

// malloc an arrary of 10 chars
originalPointer = (char *) malloc(10);

// create new pointer
char* setPtrAsNthCharOforiginalPointer;

// **** how to set it to the nth spot of ****
setPtrAsNthCharOfOriginalPointer = &originalPointer + 4;

最佳答案

删除地址运算符

too_long_name = originalPointer + 4 ;
