Do you happen to know what a flow-chart is?
pictorial representation of a program is called a flowchart
low level and high level
#include<stdio.h> void main() { int a=2,b=4; printf("Program for swapping two numbers "); printf("Numbers before swapping"); printf("a=%d and b=%d",a,b); a=((a+b)-(b=a)); printf("Numbers after swapping"); printf("a=%d and b=%d",a,b); getch(); }
there is no basic symbol in flowchart
You'll need 3 variables for this, here's a pseudo code for swapping values of 2 variables.ALGORITHM SWAPvar1 = 10var2 = 20temp = 0temp = var1 "temp = 10"var1 = var2 "var1 = 20, originally 10"var2 = temp "var2 = 10, originally 20"END SWAP
Nothing. Never do that.
It means that you swap the values of that variables EX: -==- before swapping :- Variable1 = 5; variable2 = 10; after swapping :- Variable1 = 10; variable2 = 5;
A manual flowchart is static. The advantage of an interactive Visual Logic flowchart is that it allows users to input values for various variables at runtime. When the flowchart is finished, users can then run the program behind the chart.
pictorial representation of a program is called a flowchart
To design a flowchart for inputting two numbers and swapping their values, start with a terminal symbol indicating the start. Next, use input/output symbols to prompt the user to enter the two numbers, labeling them as A and B. Then, employ a process symbol to perform the swap, which can be done using a temporary variable, such as: temp = A; A = B; B = temp. Finally, use another input/output symbol to display the swapped values of A and B, and end the flowchart with a terminal symbol.

Swapping means to swap the values of two addresses in main memory.
it's like a family tree, yourself, then flows to two parents, then flows to their 4 parents, and on and on. in otherwords, a flowchart
low level and high level
#include<stdio.h> void main() { int a=2,b=4; printf("Program for swapping two numbers "); printf("Numbers before swapping"); printf("a=%d and b=%d",a,b); a=((a+b)-(b=a)); printf("Numbers after swapping"); printf("a=%d and b=%d",a,b); getch(); }
1. Macro flowchart shows less information whereas micro flowchart shows more information. 2. Macro flowchart is easy to design as comparative to micro flowchart. 3. Macro flowchart is difficult to study and understand as comparative to micro flowchart.
