Answer 1

C 语言：
#include <stdio.h>
#include <stdlib.h>

main(){
int i,n;
n=0;
for (i=1;i<=50;i++) if (i%2==1) n++;
printf("Between 1 and 50, the total number of odd is: %d",n);
printf("\nThey are:\n");
for (i=1;i<=50;i++) if (i%2==1) printf("%d ",i);
return 0;
}

Answer 2

<script type="text/javascript">
var res = 0, arr = [];
for(var i=1;i<50;i++){
if((i%2)!==0){
res += i;
arr.push(i);
}
}
console.log('奇数求和：'+res+'\n奇数个数：'+arr.length);
</script>

Answer 3

var num=0;
var sum=0;
for(var i = 1; i < 50; i+=2)num++,sum+=i
console.log(sum);
console.log(num)
