[kadeemdagreat]

hi i have this pieceof code and im not sure as to what it is im doing wrong but i cant get this piece of code rnning any suggestions?

#include <stdio.h>
#include <math.h>

int grade input (double *a[i],double *i)
{
scanf("%l",&*a[i]);

return 0;
}


int main (void)
{
double a[i];
double i;

grade input(&a[i], &i);
printf("How many grades will be curved?\n");
scanf("%l",&i);

return 0;
}

line 4: function names can not contain embedded spaces. Either delete the space or replace it with '_' character.

And the first parameter is coded incorrectly. Looks like all you want is a pointer to a double, not an array of doubles

int grade input (double *a, double *i)

line 6: I don't know what that is but it should be this scanf("%lf", a); line 19: again use "%lf" in the format string.

actually for this code im writing i am looking for an array of doubles because currently i am not finished it but i thought i should work out the early kinks before continuting. the array of double would be for entering numerous grades. i keep getting these error messages

Many of those errors are self explanatory. Fix those first.
