Source Code - www.giraffeacad... This video is one in a series of videos where we'll be looking at programming in c. The course is designed for new programmers, and will introduce common programming topics using the c language.
Throughout the course we'll be looking at various topics including variables, arrays, getting user input, loops, conditionals, pointers, structs, and much more.

Hi Mike - Great videos. One comment regarding use of fgets(). You mention that there is an implicit newline. What you don't say, unless I missed it, is that the newline actually consumes one of the 20 bytes of storage you allocated in the name array. I.e., the code you show will really only read the first 19 characters. It does not read 20 and then add a newline. I found this out by testing your code. - Cheers - Jim

Hi Mike, This is a very instructive video. But I am mystified by one thing. You advocate use of the fgets() function when virtually every onine source I have consulted says that fgets() is deprecated and unsafe. Are these sources wrong? I've been kind of tearing my hair out trying to find a reliabl solution to the problem caused by 2 successive calls to scanf(), which as you mentioned, will leave the newline character in the buffer, causing the next call to scanf() not to work as intended. Is the ue of fgets() permissible in some situations given its status as a deprecated function? I would be interested to hear your take on this. Best, Robert Hieger

I don't get how char name is an array that will accept 10 chatacters but suddenly it able to store 10 words in it with just changing the intut function

a little issue i had: i was using this line scanf("%c", &characterr); and it just skipped to the next one. to avoid that put a space before the %c scanf(" %c", &characterr); for some reason it fixes it

scanf uses spaces as a delimiter of some sort to figure when to get the next thing. so if you have multiple scanf and there is no space in between it will not move on.

Try using fflush(stdin) after every scanf

sorry i'm learning c from another guy but i have subscribed to this channel.soi need help about somthing so please help me.so the thing is i was practicing c on codeblocks ,practicing scanf("%d %d",&a,&b); for user inputed addition of 2 numbers but when i built and ran it it didn't take the values and showed a addition of 2 huge garbage values. so how can i make it take both numbers? bellow i gave the code i wrote: #include int main() { int a,b,c; printf("Enter Two Values "); scanf("%d %d",&a,&b); c=a+b; printf("The Addition of Two Values %d And %d is %d"); return 0; } Help sir

Hey bro I copied this code and run it but it doesn't allow you to enter the grade // strings char name[10]; printf("Enter your name: "); fgets(name, 10, stdin); printf("Hello %s! ", name); // ints int age; printf("Enter your age: "); scanf("%d", &age); printf("You are %d ", age); // chars char grade; printf("Enter your grade: "); scanf("%c", &grade); printf("You got an %c on the test ", grade); // doubles double gpa; printf("Enter your gpa: "); scanf("%lf", &gpa); printf("Your gpa is %f ", gpa);
