[C言語]構造体の各メンバがメモリ上にどう配置されてるか見てみた · DQNEO日記

実験コード #include <stdio.h> struct DATA { int i1; int i2; int i3; char c1; char c2; char c3; double d1; double d2; double d3; }; int main() { struct DATA mydata; printf("address of i1 is %p\n", &(mydata.i1)); printf("address of i2 is %p\n", &(mydata.i2)); printf("address of i3 is %p\n", &(mydata.i3)); printf("address of c1 is %p\n", &(mydata.c1)); printf("address of c2 is %p\n", &(mydata.c2)); printf

構造体のメンバはメモリ空間上で順番に並ぶ（隙間がないわけではない）
