A character is entered through the keyboard. Below is a program to determine whether the character entered is a capital letter, a small case letter, a digit or special symbol. We will make use of isupper(), islower() and isdigit() functions to write this C Program. isupper() – This function will take character as parameter and will return true if the character is UPPERCASE. islower() – This function will take character as parameter and will return true if the character is lowercase. isdigit() – This function will take character as parameter and will return true if the character is a digit else it will return...

Below is the program in C language that will create and display 10 different random numbers. This program will make use of srand function in C. In order to generate random numbers, srand is usually initialized to some distinctive value. We will also make use of time function as time function will return different value at different time. The value returned by the time function will act as a parameter to srand function. Here is the code… #include #include #include void main() { int i; clrscr(); srand( (unsigned)time( NULL ) ); for (i=0; i<10; i++) printf(“%d “, rand()); printf(“\n”); getch();...

The below mentioned C Program will count number of words from a given sentence. The program will accept a sentence in a character array sen[100]. It will then calculate the number of words and display the result. #include #include #include void main() { char sen[100]; int i, count = 0; printf(“Enter a Sentence : \n”); gets(sen); for (i=0; i<strlen(sen);i++) { if (isspace(sen[i])) { count++; } } printf(“Number of words in the sentence = %d”, ++count); printf(“\n”); getch(); } Also See: Strings in C Programming Language

Below is the program in C Language that will take decimal number as input. It will then call a function that will calculate the binary equivalent of the input decimal number. #include #include int i = 0; int b[10]; void main() { int dec; int* DecimalToBinary(int n); int *p, j; printf(“Enter a decimal integer = “); scanf(“%d”, &dec); p = DecimalToBinary(dec); printf(“Binary of given decimal integer = “); for (j=i; j>=0; j–) printf(“%d”, p[j]); printf(“\n”); getch(); } int* DecimalToBinary(int n) { while (n != 1) { b[i] = n % 2; n = n / 2; i++; } if (n...
