Answer 1

您可以使用std::stringstream

#include <iostream>
#include <sstream>

void read(unsigned int add) {
    std::cout << add;
}
int main() {
    
    unsigned int x;
    std::stringstream ss;
    ss << std::hex << "478B4119"; //your string => 478B4119
    ss >> x;
    read(x);
}    

输出：

1200308505 //this number is equal to your string (478B4119) in hex

现在您可以将字符串作为参数发送给unsigned int参数化函数。
