Sorting a structure

Question

I wanted to sort this problem in C with something like bubble sort ... anyone can help

• Implement a list with 5 struct Point (Being this a point w/ X, y);
• Sort the 5 struct point (first evaluate x then y).

Example:

  // The points 
  p[0]={2,3}
  p[1]={4,5}
  p[2]={1,5}
  p[3]={4,3}
  p[4]={1,2}

  // Should become

  p[0]={1,2}
  p[1]={1,5}
  p[2]={2,3}
  p[3]={4,3}
  p[4]={4,5}

Answer 1

The OP is asking for a C solution, so here you go:

void bsortDesc(struct yourStruct list[80], int s)
{
    int i, j;
    struct yourStruct temp;

    for (i = 0; i < s - 1; i++)
    {
        for (j = 0; j < (s - 1-i); j++)
        {
            if (list[j].marks < list[j + 1].marks)
            {
                temp = list[j];
                list[j] = list[j + 1];
                list[j + 1] = temp;
            } 
        }
    }
}
