# 打印数组中任意连续元素值 ## 例子 int main(void) { int array[201]; int i; for (i = 0; i < 201; i++) array[i] = i; return 0; } ## 技巧 在gdb中，如果要打印数组中任意连续元素的值，可以使用“`p array[index]@num`”命令（`p`是`print`命令的缩写）。其中`index`是数组索引（从0开始计数），`num`是连续多少个元素。以上面代码为例： (gdb) p array $8 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199...} (gdb) p array[60]@10 $9 = {60, 61, 62, 63, 64, 65, 66, 67, 68, 69} 可以看到打印了`array`数组第60~69个元素的值。 如果要打印从数组开头连续元素的值，也可使用这个命令：“`p *array@num`”： (gdb) p *array@10 $2 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} 详情参见[gdb手册](https://sourceware.org/gdb/current/onlinedocs/gdb/Arrays.html#Arrays) ## 贡献者 nanxiao
