array is a collection of items of the same type stored in contiguous memory locations.

defining arrays:
int a[]={1,2,3};
int b[10];
int c[3]={9,0,8};
int d[10]={0,9};
int e[3]={9,8,7,6,5};//Error

finding length of an array:
input : int n=sizeof(d)/sizeof(int);
printf("%d",n);

output : 10

for printing the numbers :
for(int i=0;i<=n-1;i++)
{
printf("%d,",a[i]);

}

Here are ten programming problems that you can solve using the switch statement in C:

1. Write a program that takes a number as input and displays the corresponding month name using a switch statement.
2. Create a program that prompts the user for a day of the week (e.g., 1 for Monday, 2 for Tuesday) and prints a message indicating whether it's a weekday or a weekend.
3. Implement a calculator program that performs basic arithmetic operations (addition, subtraction, multiplication, division) based on the operator input using a switch statement.
4. Write a program that takes a character as input and determines whether it is a vowel or a consonant using a switch statement.
5. Create a program that converts a given letter grade (A, B, C, D, or F) into a corresponding GPA value using a switch statement.
6. Implement a menu-based program that allows the user to choose different options (e.g., add, subtract, multiply, divide) and perform the corresponding operation using a switch statement.
7. Write a program that takes a month number (1-12) as input and prints the number of days in that month using a switch statement.
8. Create a program that prompts the user for a shape (e.g., circle, square, triangle) and calculates the area based on the user's choice using a switch statement.
9. Implement a program that converts a given temperature in Celsius to Fahrenheit or vice versa based on the user's choice using a switch statement.
10. Write a program that takes a character as input and determines whether it is an uppercase letter, lowercase letter, digit, or special character using a switch statement.

These problems will help you practice using the switch statement in C and improve your problem-solving skills. Good luck!

Sure! Here are 10 problems related to the ternary operator in the C programming language:

1. Write a program that takes three numbers as input and uses the ternary operator to find the maximum among them.
2. Create a program that calculates the sum of all even numbers from 1 to n using the ternary operator.
3. Write a C program that uses the ternary operator to determine whether a given year is a leap year or not.
4. Implement a program that checks whether a given number is positive, negative, or zero using the ternary operator.
5. Create a program that calculates the factorial of a given number using the ternary operator.
6. Write a C program that takes two integers as input and uses the ternary operator to swap their values.
7. Implement a program that calculates the average of three numbers using the ternary operator.
8. Create a program that determines whether a given character is a vowel or a consonant using the ternary operator.
9. Write a C program that takes three integers as input and uses the ternary operator to find the minimum among them.
10. Implement a program that checks whether a given number is even or odd using the ternary operator.

These problems should help you practice using the ternary operator in various scenarios.
