conflicting types for 'main' in leetcode platform : <pre><code> #include&lt;stdio.h&gt;
 #include&lt;stdlib.h&gt;
int* twoSum(int* nums, int numsSize, int target) {
    int *a=(int *)malloc(2*sizeof(int));
    int i,j;
    for(i=0;i&lt;numsSize;i++)
         for(j=i+1;j&lt;numsSize;j++)
    if(nums[i]+nums[j]==target)
    {a[0]=i;a[1]=j;}
    return a;
}
void main(){
    int target,i;
    int numsSize;
    int b[2];
    int num[10];
    int *s;
    s=b;
    printf("Please input numsSize");
    scanf("%d",&amp;numsSize);
    for(i=0;i&lt;numsSize;i++)
    scanf("%d",&amp;num[i]);
    printf("Please input target");
    scanf("%d",&amp;target);

    s=twoSum(num,numsSize,target);
    printf("【%d,%d】",s[0],s[1]);
}

<p><strong><em>what's wrong with my code?</em></strong>
<em>I could run it smoothly on Visual Basic C++,but on the platform it implies that Line 58: conflicting types for 'main',i don't know what happened.</em></p>
