results would be like this.

Currency Note : Number

500 : 94

100 : 4

50 : 200

20 : 3

10 : 1

5 : 1

1 : 2

in a two-dimensional matrix using function. [Hint function should accept 2D array as

argument.]

write a c program to define a structure called a car. the member elements of the car structure are model(like bmw, ford...etc), production year (1999,2020,...), and lastly price. create an array of 10 cars. get input for all 10 cars from the user. then the program display complete information (model, year, price) of those cars only which are above 250000 in price or production date bigger than 2000.

5. Input Combination

by CodeChum Admin

We’ve tried adding together integers, so how about adding characters as well? Well, we can’t do that with the knowledge we have now, so let’s use placeholders to do the trick!

Instructions:

1. Input two characters in one line, separated by a space.
2. Make the characters be printed out like it’s concatenated by printing it without spaces in between using placeholders. Refer to the sample output for your reference.
3. In your scanf, don't forget to add a space in between the two placeholders for the characters because if you don't, the character that will be scanned for the second variable would actually be the space in between the two characters (because a space is also a character).

Input

1. First character

2. Second character

Output

The first two lines will contain message prompts to input the two characters.

The last line contains the two characters together.

Enter·the·first·character:·A

Enter·the·second·character:·B

AB

Now that we're done with integers, we're moving on to decimals!

Instructions:

1. Input three decimal numbers in one line separated by spaces, and make sure to store them in different variables.
2. Multiply the 1st and 2nd decimal numbers, and store the product into a variable.
3. Then, divide the product of the 1st and 2nd decimal numbers with the 3rd decimal number, then print out its quotient.

Input

1. First decimal number

2. Second decimal number

3. Third decimal number

Output

The first three lines will contain message prompts to input the three decimal numbers.

The last line contains the result in two decimal places.

Enter·the·first·number:·1.53

Enter·the·second·number:·2.25

Enter·the·third·number:·1.23

Result·=·2.80
