Thread: syntax help!!!!!!

Okay before I begin let me make this disclaimer: I'm a complete noob at programming and just started C a month ago so please don't let my ignorance irritate you.

Okay, I'm writing a program that asks a user to enter any random temperatures 26 times until the control loop variable is met. Once it is the program returns a printf that displays the avg. temp and the number of cold, hot, and warm days according to range of 60-=cold, 60-84= warm, and 85+=hot.

Now with what I have so far I believe I have everything to get the avg. part calculated but when I go to compile I get 2 undefined reference errors for the functions "get_value", and "calculate_and_print". But aren't these syntactically correct functions?

And if someone can be so kind to just summarize how I should go about writing the portion to calculate and return the number of hot, cold, and warm days I really appreciate it. I'm not looking for someone to write it, but merely to provide me with some instructions I can understand unlike my text. Below is what have so far and thanks for any and all insight! .............

Code:

/* A program to collect, calculate, and return the daily average of hot, 
   pleasant, and cold days
   Written by: Bryan Jones

*/

#include <stdio.h>


int get_n(void);
void calculate_and_print(int n);
double get_value(void);

int main(void)
{   int n;
    n=get_n();
    calculate_and_print(n);
    return 0;
}

int get_n(void)


{   
    int n;
    printf("What is the total of numbers to be entered?");
    scanf("%d", &n);
    return n;
}

void calculate(int n)

{

    double sum, average;
    int i;
    sum=0.0; 
for (i=1; i<=n; i++) 
    sum=sum+get_value();
    average=sum/(double)(n);
    printf("The average temperature is %lf\n\n",n, average);
    return;
}

Not at all. But I can't think of anything to say that wasn't said on that thread, so why say it, except to practice my ultra-sarcasm tags?

As per the other thread, you have prototyped two of your functions as:

Code:

void calculate_and_print(int n);
double get_value(void);

but you have not defined one of the prototyped functions and defined the other as:

Code:

void calculate(int n)

See the problem/difference?
