How to find the product of given digits by using for loop in C language?
The user has to enter a number, then divide the given number into individual digits, and finally, find the product of those individual digits using for loop.The logic to find the product of given digits is as follows −for(product = 1; num > 0; num = num / 10){ rem = num % 10; product = product * rem; }Example1Following is the C program to find the product of digits of a given number by using for loop −#include int main(){ int num, rem, product; printf("enter the number : "); scanf("%d", & num); ...

Enter a string at run time and read a character to replace at console. Then, finally read a new character that has to be placed in place of an old character where ever it occurs inside the string.Program1Following is the C program to replace all occurrence of a character −#include #include int main(){ char string[100], ch1, ch2; int i; printf("enter a string : "); gets(string); printf("enter a character to search : "); scanf("%c", &ch1); getchar(); printf("enter a char to replace in place of old : "); scanf("%c", &ch2); for(i = 0; i

Read MoreHow to access an array element in C language?
An array is a group of related data items that share a common name. A particular value in an array is identified by using its "index number" or "subscript".The advantage of an array is as follows −The ability to use a single name to represent a collection of items and to refer to an item by specifying the item number enables the user to develop concise and efficient programs.The syntax for declaring array is as follows −datatype array_name [size];For example, float height [50]This declares ‘height’ to be an array containing 50 float elements.int group[10]This declares the ‘group’ as an array ...
