c语言函数中多维数组的传递（以多维数组作为参数）

1、 ⾮函数形式#include

int main(void){

int a[4][3] = {{54,63,14},{65,85,78},{85,74,69},{25,65,78}}; int b[4][3] = {{25,65,74},{85,74,96},{25,87,69},{64,58,87}}; int c[4][3]; int i, j;

for (i = 0; i < 4; i++) {

for (j = 0; j < 3; j++) {

c[i][j] = a[i][j] + b[i][j]; } }

putchar('\\n');

puts(\"first examination.\"); for (i = 0; i < 4; i++) {

for (j = 0; j < 3; j++) {

printf(\"%4d\", a[i][j]); }

putchar('\\n'); }

putchar('\\n');

puts(\"second examination.\"); for (i = 0; i < 4; i++) {

for (j = 0; j < 3; j++) {

printf(\"%4d\", b[i][j]); }

putchar('\\n'); }

putchar('\\n');

puts(\"examination sum.\"); for (i = 0; i < 4; i++) {

for (j = 0; j < 3; j++) {

printf(\"%4d\", c[i][j]); }

putchar('\\n'); }

return 0;}

2、函数形式#include

void func1(const int x[4][3], const int y[4][3], int z[4][3]){

int i, j;

for (i = 0; i < 4; i++) {

for (j = 0; j< 3; j++) {

z[i][j] = x[i][j] + y[i][j]; } }}

void func2(const int x[4][3]){

int i, j;

for (i = 0; i < 4; i++) {

for (j = 0; j < 3; j++) {

printf(\"%4d\", x[i][j]); }

putchar('\\n'); }}

int main(void){

int i, j;

int a[4][3] = {{85,45,69},{36,45,87},{45,69,34},{54,78,96}}; int b[4][3] = {{58,46,24},{78,36,59},{21,46,97},{58,79,63}}; int c[4][3];

func1(a, b, c);

putchar('\\n');

puts(\"first examination.\"); func2(a);

putchar('\\n');

puts(\"second examination.\"); func2(b);

putchar('\\n');

puts(\"examination sum.\"); func2(c);

return 0;}

多维数组的传递（多维数组作为参数）：和数组的传递不⼀样，多维数组的传递在形参声明中需要注明各个维度的元素数⽬。例如：数组传递： int func1(int x[], int y). 多维数组传递： int func1(int x[4][3]).
