C长整型数中各位上为奇数的数依次取出构成新数.

1、打开Dev-C++

3、写好主函数

5、完整代码#include<stdio.h>void fun(long s,long *t){ int d; long sl=1; *t= 0; while(s>0) { d=s%10; if (d%2 == 1) { *t = d * sl + *t; sl *= 10; } s /= 10; }}void main(){ long s,t; printf("\nPlease enter s:"); scanf("%ld", &s); fun(s, &t); printf("The result is: %ld\n", t);}
