在C中将动态数组从函数返回到main

Question

returning to arrays to main, compiles but at run time gives lap2: malloc.c:2451: sYSMALLOc message. I think the error is to do with minutes() and seconds().Help would be much appreciated.

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#define N 25

int *minutes(float);
float *seconds(float);

int main ()
{ 
    int *m;
    float speed,min,sec,*s;
    printf("Enter minute and seconds\n");
    scanf("%f %f:\n", &min, &sec); 
    speed = ((min * 60) + sec) / N;
    m = minutes(speed);
    s = seconds(speed);
    printf("%p:%p\n",m,s);
    free(m);
    free(s);
    return 0;
}
int *minutes(float l)
{
    int i,*h;
    h = calloc(N,sizeof(int));
    if(!h){
        printf("memory failure\n");
        exit(1);
    }
    for(i=1;i<=N;i++)
        h[i] = ((int) l * i) / 60;     
    return h; 
}
float *seconds(float m)
{
    int i;
    float j,*k;
    k = calloc(N,sizeof(float));
    if(!k){
        printf("memory failure\n");
        exit(2);
    }
    for(i=1;i<=N;i++)
        j = i * m;
    k[i] = fmod(j,60.0);
    return k;
}

Answer 1

In your seconds(float) function this

for(i=1;i<=N;i++)
  j = i * m;
k[i] = fmod(j,60.0);

Should probably be

for (i = 1; i <= N; i++) {
  j = i * m;
  k[i] = fmod(j, 60.0);
}

At least, it seems to function when I use that... eg

Enter minute and seconds
