如何打印gsl::vector的元素？

#include <iostream>
#include <gsl/gsl_vector.h>

gsl_vector* vec = gsl_vector_alloc(n);  // n是向量的长度

for (size_t i = 0; i < n; ++i) {
    gsl_vector_set(vec, i, value);  // value是要设置的元素值
}

for (size_t i = 0; i < n; ++i) {
    double element = gsl_vector_get(vec, i);
    std::cout << element << " ";
}
std::cout << std::endl;

#include <iostream>
#include <gsl/gsl_vector.h>

int main() {
    size_t n = 5;
    gsl_vector* vec = gsl_vector_alloc(n);

    // 初始化向量
    for (size_t i = 0; i < n; ++i) {
        gsl_vector_set(vec, i, i + 1);
    }

    // 打印向量元素
    for (size_t i = 0; i < n; ++i) {
        double element = gsl_vector_get(vec, i);
        std::cout << element << " ";
    }
    std::cout << std::endl;

    gsl_vector_free(vec);
    return 0;
}
