C Program | Convert lower case to upper case
Write a Code for C Program to Convert lower case to upper case: Code: #include<stdio.h> #include<string.h> void main() { int i; char s[100]; printf("Enter a string:\n"); gets(s); for(i=0;s[i];i++) { if(s[i]>='a' && s[i]<='z') s[i]=s[i]-32; } printf("%s\n",s); } Output:
C Language | Loops | Start your journey with C | Part 4
WHAT IS LOOP : Loops are used to execute a piece of code several time according to the condition give to the loop. It means it execute same code multiple times so it saves code and also helps to traverse the elements of array. There are three types of loops in C language. They are : FOR loop. WHILE loop. DO WHILE loop. 1. FOR loop : Syntax : for(initialization;condition;increment/decrement) { ..... ...... ...... ...... // CODES ..... ..... ..... } Here is an example how FOR loop works : #include<stdio.h> void main() { for(int i=1;i<=10;i++) { printf("\n %d",i); } } Output : 2. WHILE loop : Syntax : while(condition) { ...... ...... ...... //code ...... ..... } Here is an example how WHILE loop works : #include<stdio.h> void main() { int i=1; while(i<=10) { printf...
KEY DIFFERENCE:-
ReplyDelete1) C is a Procedural Oriented language, whereas C++ is an Object-Oriented Programming language.
2) C supports only Pointers whereas C++ supports both pointers and references.
3) C does not allow you to use function overloading whereas C++ allows you to use function overloading.
4) C supports built-in data types whereas C++ supports built-in as well as user-defined data types.
5) C language follows the Top-Down programming approach whereas C++ follows a bottom-up programming approach.
6) C scan and printf are used for the standard input and output while in C++, cin and cout are given for standard input and output operations.
Wow!! That's really good.
DeleteThanks a lot.
You are most welcome. :-)
Delete1) C follows the procedural style programming.
ReplyDeleteC++ is multi-paradigm. It supports both procedural and object oriented.
2) Data is less secured in C. In C++, you can use modifiers for class members to make it inaccessible for outside users.
3) C follows the top-down approach. C++ follows the bottom-up approach.
4) C does not support function overloading. C++ supports function overloading.
5) In C, you can't use functions in structure. In C++, you can use functions in structure.
6) C does not support reference variables. C++ supports reference variables.
7) In C, scanf() and printf() are mainly used for input/output. C++ mainly uses stream cin and cout to perform input and output operations.
8) Operator overloading is not possible in C. Operator overloading is possible in C++.
9) C programs are divided into procedures and modules C++ programs are divided into functions and classes.
10) C does not provide the feature of namespace. C++ supports the feature of namespace.
11) Exception handling is not easy in C. It has to perform using other functions. C++ provides exception handling using Try and Catch block.
12) C does not support the inheritance. C++ supports inheritance.
