Arrays of structs as parameters

An array of structs is treated like any other array. If a parameter is an array of structs, a pointer to the begin-ning of an array (i.e.an array name) is the appropriate argument.

/* Store 0’s and blanks in pa[0..n-1] */

function zap (Pair pa [ ], int n) {

int k;

for (k= 0; k<n; k++)

{pa[k].a= 0; pa[k].ch= ‘ ’;}

void main( void ) {

Pair ray[42];

/* initialize ray[0..16] to 0’s and blanks */

zap(ray, 17);

}
