What is the difference between(*char) and (char*) ?

As far as I know (*char), (*float) are noty valid C constructs.

(char *) and (float *) are used to cast respectively to pointer to char and pointer to float, e.g.

char * pc = (char *) malloc( 100 );
char * pf = (float *) malloc( 100 * sizeof(float));

int(*p)[3]; declares p as a pointer to an array of three integers:

int(*p)[3];
int k[3] = {1,-2,0};
p = &k;

int *p[3]; declares p as an array of three pointers to integers:

int *p[3];
int i=5;
int j=7;
p[0] = &i;
p[1] = p[2] = &j;
