I am relatively new to C, I have to do it for school unfortunately and I am having issues with it at the easiest exercises.
Here I have to check if a number is in a certain interval, for example between 4 and 6. I made it like this.
#include <stdio.h>
int main(){
int i;
printf("Value to check Interval \n");
scanf("%s", i);
if (i>4 && i<6){
printf("%s Value is in first interval\n", i);
}
}
The scanf
to enter the number and check if it is in the interval. But even if I enter a number that is part of it, for example 5, the printf
doesn't do anything. I tried also to add an else statement for numbers outside the interval, but also there the printf
did not change anything.
It is because you have declared i variable as int
and you are taking input as string
so when it is checking condition it is getting null
value in i variable
and not able to enter if block check below code
#include <stdio.h>
int main(){
int i;
printf("Value to check Interval \n");
scanf("%d",&i);
if (i>4 && i<6){
printf("%d Value is in first interval\n", i);
}
}
try compiling your code without if condition i variable will return a null value
