C program -- Average Calculator

                            */

int main(int argc, char *argv[]){
    int average[24]; /* average[] holds the numbers that will be used when calculating */
    int number = 0; /* number holds the value a user enters when deciding how many integers will be used when calculating */
    int i = 0; /* index integer, used in both a for loop and when handling the average[] array */
    int j = 0; /* Another index, same as above */
    int add = 0; /* Adds the numbers together; used in the calculation */
    float averaged = 0.0; /* Divides add into number, which, mathematically, should determine the average of all the numbers */
    printf("This program will allow you to average a series of numbers\n");
    printf("However, this program will only allow you to do up to 25 numbers at a time, any higher is unreasonable, in my opinion\n");
    printf("Enter the amount of numbers you'd like to have averaged (max. 25): ");
    scanf("%d", &number);
    fflush(stdin);
    if(number > 25){ /* If the user enters a number over 25, number will be reinitiaalized to 25 */
       printf("Since you've entered a number over 25, I'll reinitialize the number to be 25.");
       number = 25;
    }
    for(i = 0;i < number;i++){ /* for loop to determine the values stored within average[] */
        printf("Enter the number: ");
        scanf("%d", &average[i]);
        fflush(stdin);
    }
    for(j = 0;j < number;j++) /* for loop to add the values stored in average[] together and put them in add */
        add += average[j];
    averaged = (float)add / (float)number; /* Makes add and number into floats to calculate the average of the numbers and put them in averaged */
    printf("The average of all of the numbers you have entered is %.1f\n", averaged);
    /* Calculates to the first decimal place the average of the numbers entered. */
    getchar();	
    return 0;
}

This code simply allows the user to enter a number from 1 to 25 to determine how many numbers will be calculated when averaging the set. I hope you like!

 

nice work . i have several calculators from when i first started C. i made addition,subtraction,multiplication, and division calcs. they could only use 2 numbers at once. but it was very simple and 100% efficient. i actually still have them.

just one comment on your comments, you have too many of them!
