⼆维数组的初始化（⼆维数组的赋值）⼆维数组的初始化必须在声明的时候进⾏。否则会报错。
⽐如，你应该在声明它的时候就⽴即赋值：
unsigned char bitmap[16][17]={{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0},
{255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0},
{0,0,255,255,255,0,0,0,0,255,255,255,255,255,255,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,255,255,255,255,255,0,0,0},
{0,0,0,255,255,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,255,0,0,0,0,255,255,255,255,0,0,0},
{255,255,255,255,255,0,0,0,0,0,255,255,255,255,0,0,0}};
如果改成这样就会报错：怎么给数组赋值
unsigned char bitmap[16][17];
bitmap[16][17]={{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0},
{255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0},
{0,0,255,255,255,0,0,0,0,255,255,255,255,255,255,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0},
{0,0,0,0,0,0,0,0,0,255,255,255,255,255,0,0,0},
{0,0,0,255,255,0,0,0,0,0,255,255,255,255,0,0,0},
{0,0,0,0,0,255,0,0,0,0,255,255,255,255,0,0,0},
{255,255,255,255,255,0,0,0,0,0,255,255,255,255,0,0,0}};
报错：
1>d:\vs_pro\mark_region\span_ccl\main.cpp(23) : error C2059: syntax error : '{'
1>d:\vs_pro\mark_region\span_ccl\main.cpp(23) : error C2143: syntax error : missing ';' before '{' 1>d:\vs_pro\mark_region\span_ccl\main.cpp(23) : error C2143: syntax error : missing ';' before '}'
⽽且你很难出出错的原因。
