Could someone know how this code work?

[stupendous]

we need to make a pseudo code of this code


#include <stdio.h>

int main()
{
int n,r[10],i;
printf("Enter a number to get its hexadecimal equivalent\n");
scanf("%d",&n);
for(i=0; n!=0; i++)
{
r[i]=n%16;
n=n/16;
}
i--;

for(; i>=0; i--)
{
if(r[i]==10) printf("A");
else if(r[i]==11) printf("B");
else if(r[i]==12) printf("C");
else if(r[i]==13) printf("D");
else if(r[i]==14) printf("E");
else if(r[i]==15) printf("F");
else printf("%d",r[i]);
}
printf("\n");
}
