Guidelines for working with Microsoft Visual Studio .Net

Create a new Project

Select Project Type

Create a New File

Select File Type

Save the File

Save the File

Add File to Project

Write the Code

Stage 2: Compile

Create Executable File

Stage 3: Execute

Output Window

Inserting a breakpoint

Press right mouse button and select “Insert Breakpoint”

Start Debugging

Stopping at a Breakpoint

Place the mouse on the variable of interest and check its value

Debug Windows

Choose the window that will show the variables of interest

Stepping Over

“Step over” and check the values in the “Watch” window

Run to Cursor

“Run to cursor” will run till the current cursor position

Checking a value of a variable

Checking a value of a variable

Choose “Add Watch” to a variable to the “Watch” window

Factorial

#include <stdio.h>

int main(void) {int i,n, fact=1;printf("Enter a number: ");scanf("%d", &n);

for (i =1; i<=n; i++){fact*=i;

}printf ("\nThe functorial is: %d\n", fact);return 0;

}

Stepping through a Loop

Errors

• Syntax errors – caught by compiler• Run-time errors - seen during program execution.• Reasons for run-time errors:

– Infinite loops – Division by zero – Many more …

• Important Termination Commands:– Unix: <Cntrl>-C – MS-DOS: <Cntrl>-C or <Cntrl>-break

Code and Compilation Examples

Printing Numbers

#include <stdio.h>

int main(void) {

int i;

for(i=0; i<100; i++){

printf("%d\n", i);

}

return 0;

}

Printing Numbers#include <stdio.h>int main(void){

int i,j;for(i=0; i<20; i++){

for(j=0;j<20;j++){printf("%d ", i);

}printf("\n");

}return 0;

}

Compilation Errors Example

Run Time Error Example

Don’t try this at home!!!

Infinite Loop

Don’t try this at home!!!

Use <Cntrl> C to terminate the execution
