I have to write a C program that reads a sequence of integers (positive, negative, or zero) and calculate the average of the positive integers only. If there are no positive numbers, you should display the following statement followed by a new line No positive numbers!

Here is my code, I just need help with how to ignore the negative numbers in the input sequence.

```#include<stdio.h>

int main(){

int num;  //number of elements
int i;
int sequence;  //numeber if sequence
int sum = 0.0;            //sum if the sequence
float avg;          // the average

printf("Enter the number of number in the sequence:\n");
scanf("%d", &num);

while (num < 0 || sequence[num] < 0) {
printf("No positine numbers!\n");
}

printf("Enter the sequence:\n");
for (i=0; i < num; i++) {
scanf("%d", &sequence[i]);
sum += sequence[i];
}

avg = (float) sum / num;
printf("Average is %.2f\n", avg);
return(0);
}
```

C Exercises: Counts the number of positive numbers and print the , C programming, exercises, solution: Write a C program that read 5 numbers and counts the number of positive numbers and print the average  C Program to find Sum and Average of n Number using For Loop. This C program allows the user to enter the number (n) he wishes to calculate the average and sum. Next, it will ask the user to enter individual items up to a declared number.

If you want the average of the positive numbers, you should use a different variable than num for your final avg calculation.

I would do something like this:

```    int PositiveNumCount = 0;
float avg;
for (i=0; i < num; i++) {
scanf("%d", &sequence[i]);
if(sequence[i] > 0){ sum += sequence[i]; PositiveNumCount++;}
}
avg = (float) sum / PositiveNumCount;
```

Find negative numbers from array of integers using C# program , How do you find a negative number in an array? C/C++ :: Calculate Sum And Average Of A Sequence Of Numbers Feb 17, 2014. Write a C program that calculates the sum and average of a sequence of numbers. Assume the first number specifies the number of values remaining to be entered. If the first number is less than 1, then the program should display an "Invalid Entry Please enter a

Here:

```while (num < 0 || sequence[num] < 0) {
```

you are testing `sequence[num]` before you have written any values to the array, and the test of `num` should be `num <= 0` since if there are zero values, there are also no positive values. You can only decide that there are no positive values after you have entered them all.

The array `sequence` is unnecessary - you can simply accumulate the positive values to `sum` and discard them, maintaining a count of valid values. The avoids any buffer overrun issues also.

`sum` is an `int`, but you have unnecessarily initialised it with a `double`.

```avg = (float) sum / num ;
```

is incorrect since `num` includes negative values - you need a separate count of valid values contributing to the average (unless the intent is to treat all negative values as zero).

Another issue is that you have not validated the input matched the format specifier.

```int main()
{
printf("Enter the number of number in the sequence:\n");
int num = 0 ;
int check = scanf( "%d", &num ) ;

int positive_count = 0 ;
int sum = 0 ;
if( check != 0 && num >= 0 )
{
printf( "Enter the sequence:\n" ) ;

int i = 0 ;
while( i < num )
{
int value = 0 ;
check = scanf( "%d", &value ) ;
if( check != 0 )
{
i++ ;
if( value >= 0 )
{
positive_count++ ;
sum += value ;
}
}
}
}

if( positive_count != 0 )
{
float avg = (float) sum / positive_count ;

printf( "Average is %.2f\n", avg ) ;
}
else
{
printf( "No positive numbers!\n" ) ;
}

return 0 ;
}
```

There are many issues with his posted code, including using variables before they are initialized and infinite looping paths. This is the shortest answer to his question.

How do I add negative numbers in C? : C_Programming, status (or a status above 255). signed int x = 1 -3 +5; ? You need to give us some code if you really want help. Enter number: 45.6 Average = 27.69. This program calculates the average if the number of data are from 1 to 100. If user enters value of n above 100 or below 100 then, while loop is executed which asks user to enter value of n until it is between 1 and 100.

Average of even numbers till a given even number, We can calculate average by adding each even numbers till n and then dividing sum by count. C++. Please help out here. I want to create a program whereby a user inputs several numbers (let's say 6 numbers from his/ her head). The program should then go ahead and calculate the sum of all these numbers. I however have to use a loop statement, either For statement, While statement or do/while statement. This is what I have so far:

• Please explain each line of your coding attempt, by adding a comment. It is very unclear what your thinking is. What is the idea of `sequence[num] < 0`? Where in your code is anything related to "only positive numbers"?
