void main()

int count=10,*temp,sum=0;
temp=&count;
*temp=20;
temp=∑
*temp=count;
printf("%d %d %d ",count,*temp,sum);
}



If possible explain also

void main()
{
int count=10, sum=0;
int *temp;
temp=&count;// here u r assigning address of count to temp.
*temp=20;//temp is pointing to count now. *temp means value at temp. the value at temp is count. so count is 20 now.
temp=∑//overwriting the content of temp with address of sum
*temp=count;//count value is 20 as mentioned earlier. now *temp is pointing to sum. so sum will be assigned as 20.
printf("%d %d %d ",count,*temp,sum);//all are 20 here.
}

void main()
{
int count=10, sum=0;
int *temp;
temp=&count; //Now temp will point the address of count variable.
*temp=20; //We are assigning the value to the address which temp is pointing, so the changes will reflect in count variable,bcoz temp pointing to the count variable
temp=∑ //Again we are assigning the new address to temp, so now temp will point the address of sum.
*temp=count; //value of count variable is 20 & it will assign to sum variable(look at just above line).
printf("%d %d %d ",count,*temp,sum); //all will be 20.
