Exercise_array 1(day 5)

1. Write a program that asks the user to type 10 integers of an array. The program must compute and write how many integers are greater than or equal to 10.

2. Write a program that asks the user to type 10 integers of an array. The program must output the largest element in the array, and the index at which that element was found.

3. Input values are accepted from the user into the array. Displays highest of the entered values. Prints average of values entered.

4. Write a program that accepts the following numbers in an array and reverses the array

6. Write a program that asks the user to type 10 integers of an array and an integer V. The program must search if V is in the array of 10 integers. The program writes "V is in the array" or "V is not in the array".

7. Write a program that asks the user to type 10 integers of an array and an integer value V. The program must search if the value V exists in the array and must remove the first occurrence of V, shifting each following element left and adding a zero at the end of the array. The program must then write the final array

8. Write a program that asks the user to type 10 integers of an array and an integer value V and an index value i between 0 and 9. The program must put the value V at the place i in the array, shifting each element right and dropping off the last element. The program must then write the final array

Exercise 11: dowhile-loop (day4)

1. Declare a variable which has the age of the person. Print the user’s name as many times as his age

2. The program displays even numbers from 1 to 30.

3. The program displays numbers from 10 to 0 in the reverse order

4. The program will accept integers and display them until zero (0) is entered

5.  Find the factorial of a number.

Assignment

int main(int argc, char *argv[]) {
 float x,y[12];
 int i,j;
 for (i = 0; i < 12; i++){
  printf("Month %d : ", i+1);
  scanf("%f", &y[i]);
 }
 for (i = 11; i > 0; i--){
  for (j = 11; j >= 12 - i; j--){
   if (y[j] > y[j-1]){
    x = y[j-1];
    y[j-1] = y[j];
    y[j] = x;
   }
  }
 }
 printf("Ssort descending:\n");
 for (i = 0; i < 12; i++){
  printf("%.2f ", y[i]);
 }
 printf("\nTop 3 months with highest sales amount\n");
 for (i = 0; i < 3; i++){
  printf("%.2f \n", y[i]);
 }
 return 0;
}

Exercise:For loop (day 4)

1. Declare a variable which has the age of the person. Print the user’s name as many times as his age:

2. The program displays even numbers from 1 to 30.

3. The program displays numbers from 10 to 0 in the reverse order.

4. The program will accept integers and display them until zero (0) is entered

6.  Write a program to print the series 100, 95 , 90, 85,………., 5.

Exercise: while (day 4)

Exercice 8-More conditial (day 3)

1.  Declare two variables x and y. Assign values to these variables. Number x should be printed only if it is less than 2000 or greater than 3000, and number y should be printed only if it is between 100 and 500.

2.  Write a program to show your computer’s capabilities. The user types in a letter of the alphabet and your program should display the corresponding language or package available. Some sample input ans output is given below :

                           Input                                  Output

                           A or a                                Ada

                           B or b                                 Basic

                           C or c                                 COBOL

                           D or d                                dBASE III

                           f or F                                  Fortran

                           p or P                                 Pascal

                           v or V                                Visual C++

Using the ‘switch’ statement to choose and display the appropriate message. Use the default label to display a message if the input does not match any of the above letters. 

       

3.  Accept values in three variables and print the highest value.
