i really do not know why the array is lost in the function select?
ok in codewarrior -----------------------------------------------------sort2.c #include #include extern void select(int *src,int number); int main() { int i=0; int num=0; int *array=NULL; int *array2[1]; while(num <= 0) { printf("please enter the number of elements:\n"); scanf("%d",&num); if(num > 0) { break; } } if(NULL == (array = (int *)malloc(num*sizeof(int)))) { printf("malloc failed!\n"); exit(-1); } array2[0]=array; printf("please enter the elements:\n"); for(i = 0; i scanf("%d", array+i); } select(array,num); printf("=========================\nthe result is:\n"); for(i = 0; i } return 0; } ------------------------------ sort_asm.s AREA Scopy,CODE,READONLY EXPORT select select SUBS R1,R1,#1 loop MOV R7,R1 MOV R4,R0 loop2 LDR R5,[R4] LDR R6,[R4,#4]!
