Introduction to C Programming Input
C language, as a procedural programming language, provides various ways to take input from the user. Here are some commonly used methods to input data in a C program:
The scanf() function is commonly used to read input from the standard input (keyboard). It uses format specifiers to determine the type of input to be scanned. Here is an example:
include <stdio.h>
int main() {
int num;
printf("Enter a number: ");
scanf("%d", &num);
printf("You entered: %d\n", num);
return 0;
}
The getchar() function reads a single character from the standard input, while putchar() writes a single character to the standard output. Here is an example of reading a single character:
include <stdio.h>
int main() {
char ch;
printf("Enter a character: ");
ch = getchar();
printf("You entered: ");
putchar(ch);
return 0;
}
The fgets() function is used to read a string (a sequence of characters) from the standard input. Here is an example:
include <stdio.h>
int main() {
char str[50];
printf("Enter a string: ");
fgets(str, 50, stdin);
printf("You entered: %s\n", str);
return 0;
}
C programs can also accept input from the command line arguments when the program is executed. The main() function can take arguments to read input. Here is an example:
include <stdio.h>
int main(int argc, char *argv[]) {
if(argc >= 2) {
printf("You entered: %s\n", argv[1]);
} else {
printf("No input provided through command line.\n");
}
return 0;
}
These are some common methods to take input in a C program. Choose the appropriate method based on the type of input you need to read and the complexity of the input data.
