C program to convert a lowercase string to uppercase
In this program, we will brief in on the multiple ways to convert a lowercase in C programming.
Suitable examples and sample programs have also been added so that you can understand the whole thing very clearly. The compiler has also been added with which you can execute it yourself.
In this piece, the ways used are as follows:
A string is nothing but an array of characters. The value of a string determined by the terminating character. Its values is considered to be 0.
Example:
Enter the string in lower case : 'hello'
String in lowercase ='hello'
String in uppercase ='HELLO'
As you can see in the image uploaded above, firstly, we need to enter a particular string in lowercase which we want to convert to uppercase.
The string entered here is: hello
Hence, the lowercase string, in this case, will be:
HELLO
Thus, the different methods to convert a specific lowercase string to uppercase are as follows:
- Program:
#include<stdio.h>#include<conio.h>void upper(char[]);int main(){char str[20];printf("Enter string : ");gets(str);upper(str);getch();return 0;}void upper(char str[20]){int i;printf("%s in upper case is ",str);for(i=0;str[i];i++){if(str[i]>96 && str[i]<123)str[i]-=32;}printf("%s",str);}
- Output:
Enter string : Nilesh Nilesh in upper case is NILESH
