Problem 7.6 :
Write a program to read the age of 100 persons and count the number of persons in the age
group 50 to 60. Use for and continue statements.
Solution :
#include <stdio.h>
int main() {
int age, count = 0;
for (int i = 1; i <= 100; i++) {
printf("Enter age of person %d: ", i);
scanf("%d", &age);
if (age < 50 || age > 60)
continue;
count++;
}
printf("Number of persons in the age group 50 to 60: %d\n", count);

return 0;
}

Solution C Program using else...if instead of continue:

#include <stdio.h>

#include <math.h>

int main() {

int P, n;

float r, V;

printf("Investment Table (V = P(1 + r)^n)\n\n");

printf(" P r n V\n");

printf("------------------------------\n");

for (P = 1000; P <= 10000; P += 1000) {

 for (r = 0.10; r <= 0.20; r += 0.01) {

for (n = 1; n <= 10; n++) {

// Instead of skipping any value using continue, we use conditions

if (P > 0) {

if (r >= 0.10 && r <= 0.20) {

if (n >= 1 && n <= 10) {

V = P * pow((1 + r), n);

printf("%5d %.2f %2d %.2f\n", P, r, n, V);

} else {

// do nothing or other logic if needed

} else {

// do nothing

} else {

// do nothing

return 0;

}
Output:

Question: Write a program to compute the value of Euler’s number e, that is used as the base of
natural logarithms. Use the following formula:

e=1+11!+12!+13!+…+1n!e = 1 + \frac{1}{1!} + \frac{1}{2!} + \frac{1}{3!} + \ldots + \frac{1}

{n!}e=1+1!1+2!1+3!1+…+n!1
Use a suitable loop construct. The loop must terminate when the difference between two
successive values of e is less than 0.00001.

SOLUTION:
#include <stdio.h>

int main() {
double e = 1.0, term = 1.0, prev_e = 0.0;
int i = 1;

while ((e - prev_e) >= 0.00001) {

prev_e = e;
term = term / i;
e = e + term;
i++;
}

printf("The value of e is: %.5f\n", e);

QUESTION : The present value(popularly known as book value) of an item is
given by the relationship.
P= c
Where c=original cost
d=rate of depreciation
n=number of years
p=present value after y years
If P is considered the scrap value at the end of useful life of the item, write a
program to compute the useful life in years given the original cost,
depreciation rate, and the scrap value. The program should request the user
to input the data interactively.

#include <math.h>
int main() {
float c, d, p;

// We'll scale it to fit within a positive display range, e.g., 0 to MAX_HEIGHT-1
// A simple scaling could be: scaled_y = (sin(x) + 1) / 2 * (MAX_HEIGHT - 1)
// This maps -1 to 0 and 1 to MAX_HEIGHT-1
double scaled_y_min = 0.0;

Problem 7.1:
Given a number, write a program using while loop to reverse the digits of the number.
For example,
12345
should be written as
54321
Hint: Use modulus operator to extract the last digit and the integer division by 10 to get the
n–1 digit number from the n digit number.

Answer:
#include <stdio.h>
int main()
{
int num, rev = 0;
printf("Enter a number: ");
scanf("%d", &num);
while (num > 0)
{
rev = rev * 10 + (num % 10);
num = num / 10;
