Problem Solving through Programming In C Jan 2024
Practice Program – 1 : Write a C Program to calculates the area (floating point number with two decimal places) of a Circle given it’s radius (integer value). The value of Pi is 3.14
area = PI * radius * radius;
/* Print the area with two decimal places */
printf("Area of a circle = %.2f", area);

Practice Program – 2 : Write a C program to check if a given Number is zero or Positive or Negative Using if…else statement.
if (number > 0) {
printf("Positive number.");
} else if (number < 0) {
printf("Negative number.");
} else {
printf("Zero.");
}
}

Program-01 : Write a C Program to Find the Smallest Number among Three Numbers (integer values) using Nested IF-Else statement.
if (n1<n2)
{
if(n1<n3)
printf("%d is the smallest number.", n1);
else
printf("%d is the smallest number.", n3);
}
else
{
if(n2<n3)
printf("%d is the smallest number.", n2);
else
printf("%d is the smallest number.", n3);
}
}

Program-02 : The length of three sides are taken as input. Write a C program to find whether a triangle can be formed or not. If not display “This Triangle is NOT possible.” If the triangle can be formed then check whether the triangle formed is equilateral, isosceles, scalene or a right-angled triangle. (If it is a right-angled triangle then only print Right-angle triangle do not print it as Scalene Triangle).
if(a<(b+c)&&b<(a+c)&&c<(a+b))
{
if(a==b&&a==c&&b==c)
printf("Equilateral Triangle");
else if(a==b||a==c||b==c)
printf("Isosceles Triangle");
else
if((a*a)==(b*b)+(c*c)||(b*b)==(a*a)+(c*c)||(c*c)==(a*a)+(b*b))
printf("Right-angle Triangle");
else if(a!=b&&a!=c&&b!=c)
printf("Scalene Triangle");
}
else
printf("Triangle is not possible");

Program-04 : Write a Program to find the sum of all even numbers from 1 to N where the value of N is taken as input. [For example when N is 10 then the sum is 2+4+6+8+10 = 30]
for(int i = 2; i <= N; i += 2)
{
sum += i;
}
printf("Sum = %d",sum);
