Thread: limiting printf output in scanf multi dimension character array help

I have been attempting to get this exercise right but don't know how to write the code to get desired results

Code:

 #include <stdio.h>

int main(void)


{
int x=0;
char  cName[5][21]= {0};
int  iPick;


	printf("Enter the name of 5 people\n\n");
	
	
	for(x=0;x<5;x++){
	printf("Enter name %d:", x+1);
	scanf("%s", cName[x]);
	
	
	
	printf("\n\nWould you like to add another name or view current names stored?\n");
	printf("1)\tAdd another name\n");
	printf("2)\tView names stored\n");
	scanf("%d", &iPick);
	switch(iPick){
	case 1:
	break;
	case 2:
	for(x=0;x<5;x++){
	printf("\nName %d is %s\n",x+1, cName[x]);
				
					}
}
	}
}


/*Create a program that allows a user to enter up to five names
of friends. Use a two-dimensional array to store the friends’
names. After each name is entered, the user should have the
option to enter another name or print out a report that shows
each name entered thus far*/

My problem is when I select case 2 of the switch, printf displays 5 names instead of the actual amount entered up to the point of me selecting case 2. If I entered 2 names then select case 2 I will see 5 name results with 3 of them being blank. I'd like for the blank ones to not be displayed but don't know how to code it. I tried using an if statement and ! operator to display only the names that aren't null but got compiler errors.

Code:

 for(y=0;y<=x;y++){
	printf("\nName %d is %s\n",y+1, cName[y]);

thanks
