C 언어에서 두 배열을 병합하는 방법은 무엇입니까?

J=0,k=0
for(i=0;i<o;i++) {// merging two arrays
   if(a[j]<=b[k]){
      c[i]=a[j];
      j++;
   } else {
      c[i]=b[k];
      k++;
   }
}

Enter Elements of Array1
1
2
3
4
Enter Elements of Array2
6
8
3
Elements of Array1
a[0]=1
a[1]=2
a[2]=3
a[3]=4
Elements of Array2
b[0]=3
b[1]=6
b[2]=8
Merged array is:
c[0]=1
c[1]=2
c[2]=3
c[3]=3
c[4]=4
c[5]=6
c[6]=8
