pragma mark 數(shù)組-內(nèi)存存儲(chǔ)細(xì)節(jié)

pragma mark 概念

pragma mark 代碼

#include <stdio.h>
int main()
{
    // 變量在內(nèi)存中的存儲(chǔ)
    // 由于變量的內(nèi)存尋址是從大到小,所以存儲(chǔ)數(shù)據(jù)時(shí)會(huì)從高字節(jié)
    int num = 10;   // 0000 0000 0000 0000 0000 0000 0000 1010
#pragma mark 數(shù)組的內(nèi)存細(xì)節(jié)
    /*
     // 注意:數(shù)組的存儲(chǔ)和變量有點(diǎn)不一樣,數(shù)組存儲(chǔ)元素, 是從所占用的低字節(jié)開始存儲(chǔ)
    char charValue[4] = {'l','y','h','s'};
//     charValue[0] = 0x7fff5fbff804
//     charValue[1] = 0x7fff5fbff805
//     charValue[2] = 0x7fff5fbff806
//     charValue[3] = 0x7fff5fbff807
    printf("charValue[0] = %p\n",&charValue[0]);
    printf("charValue[1] = %p\n",&charValue[1]);
    printf("charValue[2] = %p\n",&charValue[2]);
    printf("charValue[3] = %p\n",&charValue[3]);

    // &charValue == &charValue[0] == charValue
    printf("charValue = %p\n",&charValue);
    // 其實(shí)數(shù)組名就是數(shù)組的地址
    printf("charValue = %p\n",charValue);
     */
    
    // 0000 0000 0000 0000 0000 0000 0000 0101
    // 0000 0000 0000 0000 0000 0000 0000 0110

    int number[2] = {5,6};
