Thread: Find the average of random numbers:

I have the random values down but when I try to assign randValue to another integer I get an error.

I want to make an inner loop where I find 5 random number 50 times and print the average of those numbers.

I know I have the bare bones of the below, but without giving me a huge shove in the right direction can I have a poke? I have been programing for three months now. I have noticed when I do simple fun projects I learn more then what my professor assigned to me. The class is over but I want to keep building.

C++ starts in one week...

Code:

 #include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define NUMBERS 5

int main(int argc, const char * argv[])
{
    float randValue = 0.0;
    int i;

    srand(time(NULL));
    
    for (i=0; i<NUMBERS; i++) {
        randValue= 1 + (int)rand() % 10;
        printf("%6.0f\n",randValue );
    }
    
    
    
    return 0;
}

I tried add them but I was printing out the last variable so I decided to make an array. Now I get garbage values. The mathematical implementation is easy its the syntax is once again kicking my butt.

Code:

 #include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define NUMBERS 5

int main(int argc, const char * argv[])
{
    float randValue = 0.0;
    int i;
    int values[NUMBERS];
    
    srand(time(NULL));
    
    for (i=0; i<NUMBERS; i++) {
        randValue= 1 + (int)rand() % 10;
        printf("%6.0f\n",randValue );
    }
    
    for (i=0; i<NUMBERS; i++) {
    values[5]=+randValue;
    printf("%d",values[i]);
    }
    
    
    
    
    return 0;
}

you have a mistake in line 21

Code:

values[5]=+randValue;

The array named value can only be indexed from 0 t0 4 since it was declared as

Code:

Code:

 intvalues[5]

In line 11

I was asking the wrong question. What I want to do is randomly choose 6 numbers 1-99, and do that 1000 times. Out of each set find the mode. Lastly the output will be 6 random number that occurred the most.

I was thinking a struct and each node will have six random numbers. I then have to scan each node, and find the mode output the top six numbers generated randomly.

Any ideas to make this work? I am doing this for fun and I think this will test me a many areas.

Or do I need a really big array and scan the array for the top 6 numbers that occurred the most.

@CSharpener, thank you and I will use that advice and I will implement that very shortly. Since the semester is over and I have some free time I am trying to apply what I have learned,brain is in fun over drive at the moment. I will post the code in question below.
I am doing the same thing, but now I have two loops & when they both are == the number is outputted, else keep looping.
I will have a different function later for using the advice @CSharpener gave me.

I have a feeling I the code is not working correctly because my first number is always 20 which is why I switched it to 7 numbers instead of 6. Seems the numbers below 20 are random, but the first number is not.

Code:

 #include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define NUMBERS 7

int main(int argc, const char * argv[])
{
    float randValue = 0.0;
    float randValue2=0.0;
    
    int i=0,j = 0;
   
    srand(time(NULL));
    
    while (randValue!=randValue2) 
    
    for (i=0; i<NUMBERS; i++) {
        randValue= 1 + (int)rand() % 49;
        printf("%6.0f\n",randValue );
    }
    
    for (j=0; j<NUMBERS; j++) {
        randValue2= 1 + (int)rand() % 49;
        printf("%6.0f\n", randValue2 );
    }
    
    return 0;

}
