Functions and Arrays

Single dimensional arrays can be passed to functions as follows:-

float findaverage(int size, float list[])

{int i;

float sum=0.0;

for ( i=0; i<size, i++)

sum+ = list[i]

return(sum/size);

}

Here the declaration float list[] tells C that list is an array of float. Note we do not specify the dimension of the array when it is a parameter of a function.

Multi-dimensional arrays can be passed to functions as follows:

void printtable(int xsize, int ysize, float table[][5])

{ int x,y;

for (x=0, x<xsize; x++)

{ for(y=0; y<ysize, y++)

printf("\t%f",table[x][y]);

printf("\n");

}

}

Here float table[][5] tells C that table is an array of dimension Nx5 of float. Note we must specify the second (and subsequent) dimension of the array BUT not the first dimension.
