I need help with structure,
I used structure for character and then I make it in function but the problem is it doesn’t take the character with spaces,
When I use the fgets the code doesn’t allowed me to write anything
Unknown
#include <stdio.h>
struct work
{
char work_name[100];
};
struct work work_infos();
int main()
{
struct work work_infos();
}
struct work work_infos()
{
struct work s1;
printf("Enter the work: ");
//fgets(s1.work_name, 100, stdin);
return s1;
}

Are you using a for loop? (For iterating variables? Since it is C++, you can also use cout)
Anonymous
U can't << a vector
S__R
use for() { code } you cout is not in inside your for loop statement and use the index in buffer also
Anonymous
Try replace it with
for (const auto &i : buffer)
cout << i << " ";
cout << endl;

Replace i with std::bitset<8>(i)

How can I get the sum off numbers in array
Roxifλsz 🇱🇹
Nitin
sum+=a[i];
Unknown
I tried it but it doesn’t work I think because I use also structure with it
Unknown
void summary(struct work work_array[], int num_of_work)
{
int average;
int i;
int sum;
for (i = 0; i < num_of_work; i++)
{
printf("%d. Work Number %d: \t ", i + 1, i + 1);
printf("work name is %s \t", work_array[i].work_name);
printf("\t ");
printf("work percentage is %d: \t ", work_array[i].work_percentage);
printf("\n");
//sum += work_array[i].task_percentage;
}
//average = sum / num_of_work;
printf("\nThe number of works are: %d \n", num_of_work);
//printf("The average comption percentage for all: %d \n", average);
}
I use Arch
void summary(struct work work_array[], int num_of_work)
{
int average;
int i;
int sum;
for (i = 0; i < num_of_work; i++)
{
printf("%d. Work Number %d: \t ", i + 1, i + 1);
printf("work name is %s \t", work_array[i].work_name);
printf("\t ");
printf("work percentage is %d: \t ", work_array[i].work_percentage);
printf("\n");
//sum += work_array[i].task_percentage;
}
//average = sum / num_of_work;
printf("\nThe number of works are: %d \n", num_of_work);
//printf("The average comption percentage for all: %d \n", average);
}
First of all don't forget to initialize sum with 0 in the beginning

Hi

How do I add the words in the Txt file to the array in C?

How do I add the words in the Txt file to the array in C?
do you know the amount of lines of the file?
Hasan
I'll add and remove as many words as I want.
Luca
Ok so you need to dynamic allocate an array, because the number of line is unknowed.
The workflow should be:
1.) Reading file the first time to get the number of rows
2.) allocating a matrix of char depending by the number of lines
3.) reading the file a second time and storing each line inside the matrix

Do you have an example of that? Or can you write bro?

Void loop()
{
Val = digitalRead(inputPin);
If (Val == HIGH)
{
digitalWrite(ledPin, HIGH);
}
else
{
digitalWrite (ledPin, LOW);
}
}
----------------------------------------------
What I want to do
If Val == high for 5min then digitalWrite (ledPin, high)

Uhmm, did the struct declaration true ?

absolutely correct,

Anyways thank you,

You forget to clear stdin
\Device\NUL
Try to put getchar() after first scanf and in the function
\Device\NUL
That's why it didn't work
\Device\NUL
#include <stdio.h>
typedef struct work
{
char work_name[100];
};
work work_info();
int main()
{
int num_of_work;
printf("Please Enter how many works you want to manage: ");
scanf("%d", &num_of_work);
getchar(); //ignore newline
work work_array[num_of_work]; //Vulnerable to stack overflow i think
for (int i = 0; i < num_of_work; i++)
{
work_array[i] = work_info();
printf("Work Number: %d \n", i + 1);
printf("Work Name: %s \n", work_array[i].work_name);
putchar('\n');
}
}
work work_info()
{
work info;
printf("Enter the work's name: ");
scanf("%99[^\n]", info.work_name);
getchar(); //Ignore newline
return info;

Store the time you saw low for the last time. To set high, check the last low was more than 5 minutes ago

Write a c ++ program that read the grade of student:
If grade greater than 85 student get A
- If grade greater than 75 student get B
- If grade greater than 65 student get c
If grade less than 50 student fail
Repeat it until user enter (- 1) to end. Print out
1. The no of students passes and no of students failure
2. The no of students get score A
3. The no of students get score B
4. If the percentage of student passes is greater than 60%, print out "added bonus", then print the list of students (name, ID and grade) after and before bounce.
Then print again the new number of passes students. Note: new grade -old grade +5.

Hey you guys, glad to join your community!
I have a question, if you don’t mind
Pavel
#include <string>
int f(int i); // forward declaration
int main()
{
const double pi = 3.14; //OK
int i = f(2); //OK. f is forward-declared
std::string str; // OK std::string is declared in <string> header
C obj; // error! C not yet declared.
j = 0; // error! No type specified.
auto k = 0; // OK. type inferred as int by compiler.
}
int f(int i)
{
return i + 42;
}
Why does c++ needs a function declaration? I’m working as a C# developer, so it is pretty uncommon to me. Why does compiler needs function declaration, if it can take it from definition?

Hi.
Can anyone help me to make a program to write words letter by Letter and make sounds.?

is it that hard ?
Hsn
just check online for 3-4 key press sounds .. and look for online code that plays it .. write a function that runs one randomly .. and 80% of your project is done already ?

Why return 0 signifies successful termination whereas anything other than zero unsuccessful termination?
Asking in reference to the general terminology that 0 is false and non zero is true?

Is there any logic or they just went ahead with it?
