How does multi dimensional array in C work -

i creating c program tables in using multi dimensional arrays used store 2 letters , number follows:

int main() {     char x[5][3];     int y[5];      (i=0; i<5; i++)     {         printf('enter 2 characters x');         scanf('%s', x[i]);          printf('enter number y');         scanf('%d', &y[i]);     } } 

what don't understand here in for loop. example, iteration i=0, if user enters 2 characters a,b these letters stored in memory location of x? mean @ position x[0][0] or x[0][1] or other location?

i know might silly question confused here. thank in advance.

the thing here have two-dimensional array of char meaning in 1 memory location cannot store more 1 single character. stored in position 0 , 1. think approach not correct.

in case either want store char* array like:

char* tab[5] ; 

and you'll need allocate memory each line with:

tab[i] = (char *) malloc ( 2 * sizeof(char)); 

or can keep array , instead (if want sure of what's happening in memory):

for (i=0; i<5; i++) {     printf("enter first character x");     scanf("%c", &x[i][0]);     printf('enter second character x');     scanf("%c", &x[i][1]); } 

hope helps
