#include<ctype.h> //including required libraries

int countstuff(char s[]){ //Function countstuff

int cntUp=0,cntLow =0,cntDigits = 0,i=0,value; //declaring required variables

for(i=0;s[i]!='\0';i++){ //loop to iterate over the characters of string

if(isupper(s[i])){

cntUp++; //incrementing count of uppercase if it is uppercase character

}

else if(islower(s[i])){

cntLow++; //incrementing count of lowercase if it is lowercase character

}

else if(isdigit(s[i])){

cntDigits++; //incrementing count of digits if it is digit

}

}

value = cntUp*1000000 + cntLow*1000 + cntDigits; //counting value using formula given in question

return value; //returning the value

}

void main(){

char string[1000]; //declaring required variables

int value;

printf("Enter a String:");
