首先我们来看这个函数的参数和返回类型 函数的返回类型为int,函数接收的参数类型为const char* 类型。 接着看下面这一大段文字: 我们通过翻译,我们可以了解到,atoi是一个标准的库函数,它的全称是 "ASCII to Integer",用于将 ASCII 字符串转换成整数。 这个函数会解析ptr指向的字符串,直到遇到无法转换为数字

string = "New Fortran String"; logical = 0 The following example illustrates how a Fortran program can be called from a Cray C++ program: #include <iostream> using namespace std; extern "C" int fortran_add_ints_(int *arg1, int &arg2); main() { int num1, num2, res; cout << "...
stringstream Stream class to operate on strings. Objects of this class use astring bufferthat contains a sequence of characters. This sequence of characters can be accessed directly as astringobject, using memberstr. Characters can be inserted and/or extracted from the stream using any operation al...

例如,假设某个函数的原型为: void foo( int x, int y ); 该函数被C编译器编译后在符号库中的名字可能为_foo,而C++编译器则会产生像_foo_int_int之类的名字(不同的编译器可能生成的名字不 同,但是都采用了相同的机制,生成的新名字称为“mangled name”)。_foo_int_int这样的名字包含了函数名、函数参数...
