What is different between printf and scanf....

[@snehamurali6797]

Printf means .....it will print the statement in the output whereas scanf is used to get the value from the user

Refer this same tutorial......from the first video......you can clearly understand bro

[@madrohan2009]

why do you use *fp while declaring a file?

[@AsteriskYoutube]

To check whether the file exist or not and also to store the address of the file to use the file , if the file exist fopen function returns address of file but if file doesn’t present it will return null character , hope you understood

[@madrohan2009]

Thanks

[@snehamurali6797]

Normally pointer is used to store the address of the variable ........wheraeas in file concept , we want file pointer to store the address of the file .....so we are using *fp

Bro pls tell about append mode

[@AsteriskYoutube]

Append mode is similar to write mode the similarities are as follows ---- if the files present it will work and also it the file doesn’t present they both will create a new file and do the work , so here comes the difference--- if you already have written something in a file and use that file with write mode then it will clear the data of the file but append continues the file example in a file you have written hello world and u used write mode and made the program to write hi in the file so the output will be like hi but if u do this in append mode the output will be hello world hi , hope u understood and I’m poor in explaining

[@snehamurali6797]

Append mode is nothing but......it will continuously write to the existing file

[@snehamurali6797]

For example .....in file A you written as hi ......and in the same file...using append mode.... you written as guys .....you will get the result as Hi guys........
