c - 向数组中的行分配值-C编程

有谁知道我如何制作一个将十六进制值分配给4x4数组中的整行的C程序？每行将有一个值。（0x00、0xff，0x55​​和0xff）然后它需要对所有我可以做的元素求和。

#include "msp430g2553.h"

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;     // Stop watchdog timer
//--------------------------------------------------------------------------
//char type is one byte; int type is two bytes; volatile to prevent optimization
//------------------------------------------------------------------------------

volatile unsigned int i=0, j=0, sum=0;  // sum is the sum of the indices
int Zeroes = 0x00, Ones = 0xff, Odds = 0x55, Evens = 0xaa;
unsigned char ArrayFill [4][4];

//------------------------------------------------------------------------------
//  Initialize ArrayFill to 0xff
//------------------------------------------------------------------------------
{
for (i=0; i<=3; i++)
    for (j=0; j<=3; j++)
        ArrayFill[i][j] = 0xff;
}
//------------------------------------------------------------------------------
//  Fill ArrayFill with the indices values and calculate the sum of the indices
//------------------------------------------------------------------------------
{
for (i=0; i<=3; i++)
    {
    for (j=0; j<=3; j++)
        {
        ArrayFill[i][j] = ????????;
        sum=??????;
        }
    }
}
sum = sum;

最佳答案

我建议您初始化unsigned char数据类型中的十六进制值。

例如：

unsigned char hex[4][4];
    for(i=0;i<4;i++){
            for(j=0;j<4;j++){

                    scan("%s",hex[i][j]);
            }
    }
