C programs QnA

Q. If sum of two integer is 14 and if one of them is 8 then find other integer. Ans: Well, this is very simple. Simply, one integer is 8 and sum of two integers is 14. So, we need to subtract the number 8 from their sum of 14 to get the second number. So, the second number is: 14 - 8 = 6 C-Program of this task Code---> #include<stdio.h> int main () { int num1 = 8 , num2 , sum = 14 ; num2 = sum - num1 ; printf ( "The second number is: %d" , num2 ); return 0 ; }

String Concatenation using strcat() function in C-Language

In this C program we will concatenate the source string at the end of the target string using strcat() fuction. The String will be given by the User. strcat() function concatenates the source string which is source_str in this program, at the target string which is target_str in this program. strcat() takes two arguements. Like : strcat(target_str,source_str); Learn about different string functions and their use: Different String Functions input: The String. output: The input string and the concatenated string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { char source_str [ 100 ], target_str [ 100 ]= "Hello " ; printf ( "Please, Enter the string: " ); gets ( source_str ); strcat ( target_str , source_str ); printf ( "\nSource String is: " ); puts ( source_str ); printf ( "\nTarget String is: " ); puts ( target_str ); return 0 ; }

String Copy without strcpy() in C-Language

In this C program we will copy the contents of a string into another without strcpy() fuction. The String will be given by the User. Learn about different string functions and their use: Different String Functions input: The String. output: The input string and the copied string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { int n = 0 ; char source_str [ 100 ], target_str [ 100 ]; printf ( "Please, Enter a string: " ); gets ( source_str ); while ( source_str [ n ]!= '\0' ) { target_str [ n ]= source_str [ n ]; n ++; } target_str [ n ]= '\0' ; printf ( "\nThe source string is: " ); puts ( source_str ); printf ( "\nThe copied string is: " ); puts ( target_str ); return 0 ; } Download the C-Program file of this Program. Don't just read, run on your pc !!! RESULT : Please, Enter a string: Please, Follow Us too... Program

String Copy using strcpy() in C-Language

In this C program we will copy the contents of a string into another using strcpy() fuction. The String will be given by the User. strcpy() function copies the contents of one string into another. The base addresses of the target and source strings should be supplied to this function. Means it take two arguements. 1 st is the target address (where the string will be copied) and 2 nd source address (from where the string will be copied). In this case target_str is the target and source_str is the source. Like : strcpy(target_str,source_str); Learn about different string functions and their use: Different String Functions input: The String. output: The input string and the copied string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { char source_str [ 100 ], target_str [ 100 ]; printf ( "Please, Enter a String : " ); gets ( source_str ); strcpy ( target_str , source_str

Length of a String NOT using strlen() in C-Language

In this C program we will find the "Length" of a string. The String will be given by the User. Learn about different string functions and their use: Different String Functions input: The String. output: The Length of the String will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { int n = 0 , len = 0 ; char arr [ 100 ]; printf ( "Please, Enter the String : " ); gets ( arr ); while ( arr [ n ]!= '\0' ) { len ++; n ++; } printf ( "\nThe length of the string is : %d" , n ); return 0 ; } Download the C-Program file of this Program. Don't just read, run on your pc !!! RESULT : Please, Enter a string : Hello World String Length is : 11 -------------------------------- Process exited after 11.28 seconds with return value 0 Press any key to continue . . .
