Excusez mon français pauvre mai the difference between getting the computer code for a particular letter of character and something else is easier to answer if I know what the other way is, veuillez terminer la question
ALU stands for arithmetic and logic unit. The ALU does complex calculations, so by having two it gets the job done faster. This may not really make a difference if your an average user, although if you do AutoCAD and stuff that requires rendering then it will make a HUGE difference.
It means that a machine gets it for you
it only gets opened on some formats
It gets you a virus called the bortractic

printf , scanf , getchar, putchar, getc are the other operators in C except gets and puts..
read, fread, gets, fgets, getc, fgetc, getchar, getch
the getchar function waits the user hit a key followed by return key. Upon the return key hitted by the user the function returns the key. But the scanf can be used for various & different user entered data including text, integer, float and so on. in spite of getchar the delimeter keys for scanf function are tab, space and return key; so when a space entered by the user in the input the scanf will end the input and waits user enter the return key. You must take in mind that just the fragment of input that is behind these delimeters will be considered as legal input for the scanf and the remaninder will be escaped.
gets()Reads characters from stdin and stores them as a string into str until a newline character ('\n') or the End-of-File is reached.The ending newline character ('\n') is not included in the string.getchar()Returns the next character from the standard input (stdin).It is equivalent to getc with stdin as its argument. === ===
Gets a single key stroke from the keyboard.
The scanf() function is a commonly used function to input information during the execution of a program. scanf() function has its prototype in the stdio.h header file. To accept and display a number: int num; printf("Enter a number: "); scanf("%d",&num); printf("You entered %d",num); To accept and display a character, replace %d with %c and make num a character variable [char]. Plus: gets, fgets, read, fread, getchar, getc, fgetc, getch...
The getchar() function gets a single character from stdin. Here is a very basic example: #include <stdio.h> int main() { char ch; do { ch = getchar(); putchar(ch); } while (ch != ';'); return 0; } It reads from data you input and prints it again of the screen after you press key. It works until it reaches ";" symbol. The getchar() function is equivalent to getc(stdin).
formatted functions::: Follows a fixed format like scanf,printf Unformatted functions:::Do not have fixed format like gets,getchar
#include,stdio.h>main(){char string1[20],string2[20]printf("enter the first string");scanf("%s",string1);// reading the string1printf("enter the second string");scanf("%s", string2);// reading the the string2printf( "the first string is %s",string1);// printing the string1printf("the second string is %s",string2);// printing the string2}the problem of using scanf is that it does not take space. so we can use gets for it.ie instead of scanf("%s",string1); we can use gets(string1); .
Examples: recv, read, fread, gets, fgets, scanf, fscanf
The 'gets' routine is designed to return all characters up to the end of the line, including embedded spaces.The 'scanf' routine returns values based on a format; if you are using the %s format conversion, it will stop when it encounters a white-space character (such as the space).The two routines are used for different things. With 'gets' it is assumed that you will parse and convert anything in the line yourself, whereas the scanf routine helps to parse items out in the format that you want (most of the time).see: In_c_language_strings_why_gets_function_allows_blank_spaces_but_scanf_function_does_not
Commonly used input/out functions in C are:* printf( )* scanf( )scanf() it is the standard input functions. It is used to get the data from the input devices, which is by default a keyboard, at run time, or execution time. Its general format is:scanf("one or more format specifier",& one or more variables separated by comma);For example:scanf("%d",&a);scanf("%d%,&a,&b);printf() It is the standard output functions it is used to show the data to an output device, which is by default a monitor screen, at run time, or execution time. Its general format is:In case of displaying the message:printf("Type the message here");for example:printf("Hello World");In case of printing the value:printf("one or more format specifier", & one or more variables separated by comma);for example:scanf("%d",&a);scanf("%d%f",&a,&b);
