C Program to display the sequence BCA1, BCB2, BCC3, BCD4........................

In this example of C tutorial, we will take number of terms input from the user and print the above mentioned series in the console/screen.

Write program to display the sequence BCA1, BCB2, BCC3, BCD4...................

Program:

================================

#include<stdio.h> int main(void) { int n, i, k; printf("Enter the number of terms: "); scanf("%d",&n); for(i=0;i<n;i++) { k=i/26; printf("%c%c%c%d ",66,67,i+65-26*k,i+1); } return 0; }

================================

Output:

================================

Enter the number of terms: 4 BCA1 BCB2 BCC3 BCD4

================================

Explanation of the program:

# : If any line start with #, it is a pre-process only that line. Special symbol (#) to indicate the pre-processor directive.

include : pre-processor directive. I include important file in the C program.

stdio.h : This file contains functions such as printf() and scanf() to print in the screen and taking input from the user.

main() : The C program execution starts from this line. The main() function is called by the operating system (O/S).

int : It is an Integer data type.

scanf() : It is a function defined in the stdio.h header file, to take the date from the user.

%d : It is the format specifier for the Integer data type.

& : Address of any variable in the memory.

printf() : It is a function defined in the stdio.h header file, to print or send output to the screen/consol.

return 0 : This statement is to Exit the program. It tells the operating system (O/S) that the program has run successfully, as 0 means success. In place of 0 we can use any number like 1, 2,… but the general convention is to write 0.
