This document discusses computer problem solving skills and programming languages. It defines a computer program as a sequence of instructions that causes a computer to perform a specific task. Examples of programs are provided in several languages like ALGOL, BASIC, C, and Fortran to display or print text. Programming languages are designed to communicate instructions to computers and examples given include BASIC, Fortran, COBOL, C, Pascal, ALGOL, Logo, Assembly, Java, and Prolog. Programming languages are classified as assembly language, high-level languages, and machine language.

Arc. Alli Abiodun Ismail

2. objectives
• Identify a computer program;
• Define a computer programming language;
• Give examples of computer programming languages.

3. Computer Program
• A computer needs written instructions to perform specific tasks.
These written instructions are called programs.
• Technically, a program is defined as a sequence of instructions written
to perform a specific task with a computer.
• It is an organized list of instructions that, when executed causes the
computer to behave in a predetermined manner.

4. Examples
• In ALGOL
BEGIN
DISPLAY( “Welcome to Esteem”)
END
• In BASIC
PRINT “Nigeria is great”
• In C
(programming language)
#include <stdio.h>
Int main (void)
{ printf(“Nigeria is greatn”)
{ return 0

5. Examples cont.
• In Fortran
Program Nigeria
Print*, ‘Nigeria is great’
End program Nigeria

6. Programming Language
• A programming language is an artificial language that is designed to communicate instructions to a machine,
particularly computer. A programming language can be used to create programs which control the behavior
of a machine particularly a computer.
• Examples
• BASIC;
• Fortran
• Cobol;
• C;
• Pascal
• Algol;
• Logo;
• Assembly language;
• Java;
• Prolog e.t.c
