In Problems 1 through 7, draw a flowchart to perform the steps indicated.
Then give the corresponding C statements. Assume that the variables have
been declared and have reasonable values.

     1: If time is greater than 15.0, increment time by 1.0.
     2: When the square root of poly is less than 0.5, print the value of poly.
     3: If the difference between volt_1 and volt_2 is larger than 10.0,
         print the values of volt_1 and volt_2.
     4: If the value of den is less than 0.05, set result to zero; otherwise,
        set result equal to num divided by den.
     5: If the natural logarithm of x is greater than or equal to 3,
        set time equal to zero and decrement count.
     6: If dist is less than 50.0 and time is greater than 10.0,
        increment time by 2; otherwise, increment time by 2.5.
     7: If dist is greater than or equal to 100.0, increment time by 2.0.
        If dist is between 50 and 100, increment time by 1.
        Otherwise, increment time by 0.5.

Convert the following nested if/else statements to a switch statement:

if (rank==1 || rank==2)
   printf("Lower division \n");
else
{
   if (rank==3 || rank==4)
      printf("Upper division \n");
   else
   {
      if (rank==5)
         printf("Graduate student \n");
      else
         printf("Invalid rank \n");
   }
}
