将字符串转换为 double

Question

我正在尝试将字符串 (const char* argv[]) 转换为 double 精度浮​​点数:

int main(const int argc, const char *argv[]) {
    int i;
    double numbers[argc - 1];
    for(i = 1; i < argc; i += 1) {
        /* -- Convert each argv into a double and put it in `number` */
    }
    /* ... */
    return 0;
}

谁能帮帮我？谢谢

使用sscanf (Ref)

sscanf(argv[i], "%lf", numbers+i);

或strtod (Ref)

numbers[i] = strtod(argv[i], NULL);

顺便说一句，

for(i = 1; i < argc, i += 1) {
//-----------------^ should be a semicolon (;)
