Find number of uppercase and lowercase letters in a string
Here given code implementation process.
// C Program
// Count number of uppercase and lowercase letters in a sentence
#include <stdio.h>
void count_letters(char str[],int size)
{
int lowercase=0,uppercase=0;
for (int i = 0; i < size; ++i)
{
if(str[i] >= 'a' && str[i] <= 'z')
{
lowercase++;
}
else if(str[i] >= 'A' && str[i] <= 'Z')
{
uppercase++;
}
}
//Display Result
printf("String : %s\n",str );
printf("Lowercase : %d\n",lowercase );
printf("Uppercase : %d\n",uppercase );
}
int main()
{
char str1[]="This Is simple TEXT";
//Get the size
int size = sizeof(str1)/sizeof(str1[0])-1;

char str2[]="DeTectThisLanGuages";
//Get the size
