#include <stdio.h>
#include <math.h>

int main() {
    float g1, g2, c1, c2, dismul, cadd, csub, dis;

    printf("Enter the latitudes of the places (L1 and L2): ");
    scanf("%f %f", &c1 ,&c2);
    printf("Enter the longitudes of the places (G1 and G2): ");
    scanf("%f %f ", &g1, &g2);
    cadd = cos(c1 + c2);
    csub = cos(g2-g1);
    dismul = cadd * csub;
    dis = 3963 * acos(dismul);
    printf("The distance between the places is:%f\n", dis);
    return 0;
}

我写了这段代码来给出两点之间的距离，但是当我运行它时，它不会给出最后一个，printf直到我输入任何字母并按回车键。
