定义函数时C++代码编译失败[关闭]

Question

我的代码编译失败，我收到这些错误消息。我看过类似的问题，但似乎没有什么是对的。我不明白是什么导致了问题，因为我已经声明了我的函数并在 main 下定义了它。

declaration is incompatible with "void reprchar(char ch, int n)" (declared at line 18)C/C++(147) [4,6]
variable or field 'reprchar' declared void gcc [4,14]
'reprchar' was not declared in this scope gcc [7,5]
expression preceding parentheses of apparent call must have (pointer-to-) function type C/C++(109) [7,5]
expression preceding parentheses of apparent call must have (pointer-to-) function type C/C++(109) [9,5]
expression preceding parentheses of apparent call must have (pointer-to-) function type C/C++(109) [14,5]
declaration is incompatible with "void reprchar" (declared at line 4) C/C++(147) [18,6]

代码是

#include <iostream>
using namespace std;

void reprchar('a', 54);

int main() {
    reprchar('*', 45);
    cout << "Data type      Range" << endl;
    reprchar('-', 23);
    cout << "char       -128 to 127" << endl
         << "short      -32,768 to 32,767" << endl
         << "int        System Dependent" << endl
         << "double     -2,147,483,648 to 2,147,483,647" << endl;
    reprchar('*', 45);
    return 0;
}

void reprchar(char ch, int n) {
    for(int i=0; i<n; i++) {
        cout << ch;
    cout << endl;
    }
}

Answer 1

void reprchar('a', 54); 无效

用正确的原型替换

void reprchar(char, int);
