This is the first program we wrote today and I need help understanding some stuff cause I am used to c++
C Code:
#include <cstdio>#include <cstdlib>#include <time.h>using namespace std
;int main
(void){ int deja
; int num1
, num2
; printf("This program gets 2 numbers from the user and randomly adds or subtracts them \n"); printf("Enter 2 numbers and hit the ENTER key after each one \n"); scanf("%i", &num1
); scanf("%i", &num2
); printf("%s, %i, %i \n", "The 2 numbers are : ", num1
, num2
); srand(time(NULL
)); deja
= rand()%2; if (deja
== 1) { printf("%s, %i \n","The sum is", num1
+ num2
); } else { printf("%s, %i \n", "The difference is" ,num1
- num2
); } return EXIT_SUCCESS
;}
Everytime I run it, it does not print these first 2 lines
C Code:
printf("This program gets 2 numbers from the user and randomly adds or subtracts them \n");printf("Enter 2 numbers and hit the ENTER key after each one \n");
Instead goes to the scanf and eventually waits for the user to enter both numbers before displaying the first 2 printf functions.
Also is there a different way to do the rand function that is easier to understand to someone who has never used it before?
When it runs, it shows this:
Code:
This program gets 2 numbers from the user and randomly adds or subtracts them
Enter 2 numbers and hit the ENTER key after each one
The 2 numbers are : , 6, 5
The difference is, 1
Is there a way to prevent it from showing the comma before the numbers?
