C Programming Tutorial 5, Getting User Input

[mairooni]

personally I find the "see you guys" bit a little funny because when I heard it what I thought was "c you guys"....anyways I love your videos and I really appreciate your help!THANK YOU! <3

It's because you're only reading in a single character from the console. If you want to read multiple, or a string, then use this code:

char myStr[50];
scanf("%s", myStr);

I'm sure that I cover this in later tutorials though.

It's been a week and im learning more and more every day i thank you sir these are all the ones iv memorized below :D

int main;
int n1 = 5;
int n2 = n1;
int n3 = n1 + n2;
printf("%i", n3);
return 0;

int main;
float f1 = 2.5;
float f2 = 2.5;
float f3 = f1 + f2;
printf("%.0f", f3);
return 0;
 
int main;
char c1 = 'A';
printf("%c", c1); 
return 0;

int main;
int n1 = 0;
printf("Enter first number: ");
scanf("%i", &n1);
int n2 = 0;
printf("Enter second number: ");
scanf("%i", &n2);
printf("The Answer Is %i", n1 + n2);
return 0;

int main;
float f1 = 0;
printf("Enter first number: ");
scanf("%f", &f1);
float f2 = 0;
printf("Enter Second Number: ");
scanf("%f", &f2);
printf("%.1f", f1 + f2);
return 0;

i like how fast paced yours videos are

[godsword]

thanx but honestly u moved so fast i have to pause cause i wanna understand what im doing, but your great bro been a lot of help i plan on taking computer science as a major in college so trying to practice certain things now

Don't we need a gap before %c? I heard somewhere (and experienced once) that not doing so with break the code.
So code should be something like:
char s;
printf("enter char");
scanf(" %c", &s);
printf("%c", s)
?

[Kaneyren]

just started your videos and I'ma little curious. Why are you using scanf instead of cin>>? is there a major difference between the two?

[Grkgermn]

Interesting. I suggest, however, to make the examples more interesting/usable.

[quiroz]

are there other ways of making this kind of program cause i had seen other ways of doing this kind of user input 

[rzezzy]

Might I ask what compiler you use and where I can download it?

[SH-fpom]

Write( in c language) a function that asks the user
to enter a statement than the program display how many vowels

[MrMehran]

thanks alot for video, , , good job :-)

[ahmed]

what's the purpose of int num = 0 ; in the beginning?

[TheKurtPrice]

Woah there buddy. You should never use scanf because it doesn't check for overflow and can make your application insecure.

[jameykelly]

why when the char code is put after the previous int code, does the program skip the input part? it doesn't have that problem when the char code is first.

[ryanpvw]

#include <stdio.h>
#include <stdlib.h>
int main()
{
    float num = 0;
    printf("Please enter a number: ");
    scanf("%f", &num);
    float num2 = 0;
    printf("Please enter a second number: ");
    scanf("%f", &num2);
    printf("The sum is: %.2f\n", num + num2);
    printf("The difference is: %.2f\n", num - num2);
    printf("The product is: %.2f\n", num * num2);
    printf("The quotient is: %.2f\n", num / num2);
    return 0;
}
I suck at c....im used to java. I have been coding that for three years. Still used to jframes, event handlers, extension filters, and opengl :(

Hey guys how do you effectively get user input on a continuing basis without struggling back and forth with the input buffer?? fflush(stdin) has not worked for me, neither has using scanf(" %c") or "%c\n" . Every time, the input buffer feeds a newline into the program. THe only solution I have found is to use getchar() on Windows 10. Thanks.
