[MIPS] 輸入、輸出數字範例
程式操作很簡單，輸入十一個數字於陣列中，並將這十一個數字輸出。
使用 QtSpim 操作環境。
#include <stdio.h>
int main() {
int array[11], size = 11;
int *t1 = array, t2 = size;
int t0 = 0, v0;
int s0 = 0;
inputi:
scanf("%d", &v0);
*(t1+t0) = v0;
t0++;
s0++;
if(s0 != t2)
goto inputi;
s0 = 0;
t0 = 0;
outputi:
printf("%d\n", *(t1+t0));
t0++;
s0++;
if(s0 != t2)
goto outputi;
return 0;
}
約略的相同 .cpp
