Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a variable for storing the output signal.

Simulink

double [1];

Drag options to blanks, or click blank then click option'

Aint

Boutput_signal

Csignal_output

Dfloat

💡 Hint

Common Mistakes

Using a data type instead of a variable name.

Choosing a variable name that does not match the output.

The variable output_signal is declared as a double to store the output value.

2fill in blank

medium

Complete the code to assign the input value to the variable.

Simulink

[1] = input_signal;

Drag options to blanks, or click blank then click option'

Asignal_input

Binput_signal

Coutput_signal

Dresult

💡 Hint

Common Mistakes

Assigning the variable to itself.

Using the input variable on the left side.

The variable output_signal receives the value from input_signal.

3fill in blank

hard

Fix the error in the function call to update the output.

Simulink

updateOutput([1]);

Drag options to blanks, or click blank then click option'

Bsignal

Cresult

Dinput_signal

💡 Hint

Common Mistakes

Passing the input variable instead of the output.

Using an undefined variable.

The function updateOutput should be called with the output variable output_signal.

4fill in blank

hard

Fill both blanks to create a for loop that iterates over 10 elements and sums them.

Simulink

double sum = 0;
for (int [1] = 0; [2] < 10; [1]++) {
    sum += data[[1]];
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different variable names in the loop header.

Using a variable name not declared in the loop.

The loop variable i is used consistently to iterate from 0 to 9.

5fill in blank

hard

Fill all three blanks to create a dictionary-like structure in C using structs and initialize it.

Simulink

typedef struct {
    char* [1];
    int [2];
} [3];

[3] data[] = { {"speed", 100}, {"power", 200} };

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up field names.

Using inconsistent struct names.

The struct Parameter has fields name and value to hold key-value pairs.
