#include <stdio.h> int convertToInteger(char* expression) { int result = 0; int i = 0; while (expression[i] != '\0') { if (expression[i] >= '0' && expression[i] <= '9') { result = result * 10 + (expression[i] - '0'); } i++; } return result; } int main()...
它分为两部分。第一部分是，正如你可能知道的，C中的字符串表示为字符数组。（这很好，这甚至算不上"...
You can't assign a char* pointer to an int variable, unless you type-cast it, which is not what you need in this situation. You need to parse the char* string using a function that interprets the content of the string and returns a translated integer, such as std::atoi(), std::s...
几乎可以肯定，您使用的是int为4字节的体系结构，以及先存储“最小”字节的little-endian体系结构。因此...
5 Pointers to string in functions 283 What is the difference between char array and char pointer in C? 0 How casting of char pointer to int pointer works? 3 Why the char has to be a pointer instead of a type of char? 1 Printing (Char*)(Void*) works in main program but ...
2.1、TYPE *pointer_array[SIZE] 2.2、" TYPE "是数据类型;" SIZE "是正整数。 2.3、涵义:pointer_array存储"SIZE"个指针,“SIZE”个指针是"TYPE类型的指针"。 3、int *int_pta[10]:int_pta是存储10个指针的数组,这10个指针的是“int类型的指针”。
int等于4，整数存储在little-endian中。一个简单的程序可以用十六进制显示数据的内容：

因为char是16位的，采取的Unicode的编码方式，所以char就有以下的初始化方式： //字符，可以是汉字，因...
Unless you provide some way for the code to determine what size of object the pointer points to, dereferencing the pointer when it points to an object smaller than a 32-bit int will cause undefined behavior. Read it again. What I said was converting a pointer value to a different typ...
