A personal understanding of an int array and a char array

In a char array, either one-dimensional or two-dimensional, each piece of data is separated by the provided starting address into a string that is processed as the program executes. so the function of char[] is to provide only the corresponding starting address as a formal parameter.

Char[] instead of using the = sign for exchanging content with each other, use strcpy (A, A, a), where a is the starting address for "assigned" char[, and B is the starting address of the "value to assign" char[]. To modify one of these characters, you can use the = sign

In addition for example char* a= "ABCD" and char b[5]= "ABCD"; the difference is that B can arbitrarily modify a character in a character array, and a cannot be modified after initialization.

But a can change the address it points to, and B is an array named "Pointer constant" and cannot modify its point to address.

The two-dimensional int array int a[3][10], which is to be processed by entering one of the 3 one-dimensional arrays as formal parameters into the function. For example:

#include <stdio.h>
void and1 (int b[])
{
B[1] = b[1] + 1;
}
int main (void)
{
int a[3][2] = {1,2,3,4,5,6};
AND1 (a[2]);
printf ("%d", a[2][1]);
return 0;
}

The purpose of this program is to add a second element of the third array in the two-dimensional int array. Why do you write this, because the int array is a numeric value that is processed according to 4 bytes ,

Formal parameter b[] just want to provide a starting address for the one-dimensional array you want to work with.
