[Tutorial 7] 1.Write a program that subtracts the value 15 from 87 and displays the result, together with an appropriate message, at the terminal.

#include <stdio.h>
int main(void)
{
int sum;

/* COMPUTE RESULT */
sum = 87 - 15;

/* DISPLAY RESULTS */
printf ("The answer is %i \n", sum);

return 0;
}
This C program calculates the result of subtracting 15 from 87 and then displays the result as "The answer is 72" using the `printf` function.

Output:
The answer is 72

[Tutorial 6 ] 2. Write a program that prints the following text at the terminal.

i) * * * * * * * * * * * * * * * * * * * * * #include <stdio.h> int main( void ) { int row,column; for (row=1;row<=6;row++) { for( column=1;column<=row;column++) { printf( "*" ); } printf( "\n" ); } return 0; } This C program prints a pattern resembling a right triangle with asterisks, where the number of asterisks in each row increases from 1 in the first row to 6 in the last row. It achieves this using nested loops: the outer loop controls the number of rows, and the inner loop determines the number of asterisks to print in each row. After printing the required number of asterisks in each row, a newline character is printed to move to the next row. Thus, the result is a right triangle pattern made of asterisks.

Compilation process in c

Image
   What is a compilation?        C is a programming language that converts source code into object code or machine code. The conversion process has four steps: Pre-processing, Compiling, Assembling, and Linking.      The preprocessor eliminates all the comments from the source code and carries out the preprocessor directives. For instance, it substitutes the directive <stdio.h> with the contents of the 'stdio.h' file.       The following are the phases through which our program passes before being transformed into an executable form:         Preprocessor         Compiler         Assembler         Linker Preprocessor A source code file is a text file that contains instructions written in the C programming language. The file name has a ".c" extension to indicate its format. Before compiling the source code, a preprocessor analyzes and modifies i...
