Question

Name this program count.c-The program takes the name of an input file as its single command line argument and uses a function to count the number of upper-case letters, lower-case letters, and digits found in each string within the file. The main 2. program is shown below. You must write the function counts. This function is passed a string and returns the number of uppercase letters, lowercase letters, and digits through the second, third, and fourth parameters. The file DATA Alabama ./a. out DATA Alabama has 1 uppercase, 6 lowercase, and 0 digits has 4 uppercase, 4 lowercase, and 4 digits 1234crimABCD #%$@#$ has 0 uppercase , 0 lowercase, and 0 digits #8$@#$ | #include #include #include void counts (char *, int *, int *, int ) int main (int arge, char *argvl) ( FILE *fp = fopen (argv [1], char str [100]; fscanf(fp, "%s", str); while feof (fp) "r"); int upper, lower, digit; counts (str, upper, &lower;, &digit;); printf("%s has %d uppercase, %d lowercase, and %d digits ", str, upper, lower, digit) str); fscanf (fp, "%s", return 0;

Explanation / Answer

void counts(char *str, int *upper,int *lower,int *digit) {

for(int i=0;i<strlen(str);i++) {

// Checking Upper Case Latter in string

if(str[i]>='A' && str[i]<='Z') {

++*upper;

}

//Checking Lower Case latter in string

else if(str[i]>='a' && str[i]<='z') {

++*lower;

}

//Checking Digit in string (Comaring with its ASCII values)

else {

if(str[i]-'0'>=0 && str[i]-'0'<=9) {

++*digit;

}

}

}

}
