02. Find the minimum and maximum of sequence of 10 numbers.
04. Write a program to generate and display a table of n and n2, for integer values of n
ranging from 1 to 10. Be certain to print appropriate column headings.
05. A triangular number can also be generated by the formula
triangularNumber = n (n + 1) / 2
06. The factorial of an integer n, written n!, is the product of the consecutive integers 1
through n. For example, 5 factorial is calculated as
5! = 5 x 4 x 3 x 2 x 1 = 120
1 + 1/2 + 1/3 + 1/4 + 1/5 ... 1/n terms
Test Data :
Input the number of terms : 5
Expected Output :
1/1 + 1/2 + 1/3 + 1/4 + 1/5 +
Sum of Series upto 5 terms : 2.283334

10.Assume a village has 20 houses. Input electricity unit charges and calculate total
electricity bill according to the following criteria:
- For first 50 units Rs. 0.50/unit
- For next 100 units Rs. 0.75/unit
- For next 100 units Rs. 1.20/unit
- For unit above 250 Rs. 1.50/unit
- An additional surcharge of 20% is added to the bill
The output should be as follows:
Serial Number House Address Units Surcharge Amount to be paid
#include <stdio.h>
int main()
{
int numHouses = 20;
float unitCharges, totalBill, surcharge, amountToBePaid;
int units;
printf("Enter electricity unit charges: ");
scanf("%f", &unitCharges);
printf("Serial Number\tHouse Address\tUnits\tSurcharge\tAmount to be paid\n");
for (int i = 1; i <= numHouses; i++)
{
printf("%d\t", i);
printf("House %d\t", i);
printf("Enter units consumed for House %d: ", i);
scanf("%d", &units);
if (units <= 50) {
totalBill = units * 0.50;
} else if (units <= 150) {
totalBill = 50 * 0.50 + (units - 50) * 0.75;
} else if (units <= 250) {
totalBill = 50 * 0.50 + 100 * 0.75 + (units - 150) * 1.20;
} else {
totalBill = 50 * 0.50 + 100 * 0.75 + 100 * 1.20 + (units - 250) * 1.50;
}
surcharge = 0.20 * totalBill;
amountToBePaid = totalBill + surcharge;
printf("%d\t%.2f\t%.2f\n", units, surcharge, amountToBePaid);
}
return 0;
}
