Find a C language program: input a positive integer, the number required to be output in reverse order. Such as input 1234, output 4321

int main(int argc, char* argv[]){ int input; int ret,num; printf("Input a int:"); scanf("%d",&input); for(;;) { num=input%10; input=input/10; printf("%d",num); if(input

Love number language for four numbers

C language to determine a number is a few digits and output each digit
Using C language: input a number to judge how many digits it is and output each digit,

//Input a number to judge how many digits it is and output each digit
#include
main()
{
unsigned long num,i,count=0;
printf("please input the number:");
scanf("%d",&num);
Printf ("from low to high::);
printf("%d ",num%10);
for(i=1;num/=10;i++)
printf("%d ",num%10);
Printf ("total% d digits", I));
return 0;
}

Add a number to the numerator and denominator of 5 / 13 to get 1 / 2. What is the number added at the same time?
List the formulas

The answer is 3. (5 + x) / (13 + x) = 1 / 2 2 * (5 + x) = 1 * (13 + x) 10 + 2x = 13 + X 2x-x = 13-10

Is one and a half hours the same as one hour and a half

It's the same
It's just a different way of writing
The first way is to use the plural hours
The second is singular hour
That's the difference
ONE AND A HALF POUNDS
ONE POUND AND A HALF
This is also the case

The range of the function y = x + 1 / X is

Discussion by situation
1. When x > 0, x + 1 / X ≥ 2; [inequality theorem, a + B ≥ 2 √ AB]
2. When x0, then: (- x) + (- 1 / x) ≥ 2, that is: x + 1 / X ≤ - 2;
Then: the range of function y = x + 1 / X is (- ∞, - 2] ∪ [2, + ∞)

How do I think of Luo Jiaying

As shown in the figure, point I is the heart of △ ABC, the extension line of AI intersects at point D, and the circumcircle of △ ABC intersects at point E. (1) prove that IE = be; (2) if ie = 4, AE = 8, find the length of de

(1) It is proved that: connecting IB. ∵ point I is the heart of △ ABC, ∵ bad = ∵ CAD, ∵ ABI = ∵ IBD = ∵ ABI = ∵ CAD + ∵ IBD = ∵ IBD + ∵ DBE = ∵ IBE, ∵ be = ie

Let f (x) = x & # 179; + BX & # 178; + CX (x ∈ R), we know that G (x) - F ′ (x) is an odd function, and find the value of B and C
(2) finding monotone interval and extremum of G (x)

1. F ′ (x) = 3x & # 178; + 2bx + C, let H (x) = g (x) - F ′ (x), from the topic meaning, H (x) cross the origin, is an odd function
No expression for G (x)?
