Hi i am having problem with strings using for loop. When i enter input abc, strlen shows that string length is 3 but when i enter abc d string length still shows 3 and i think loop stop when it sees space.
here is my program
Thanks for your helpCode:/* Caesar Cipher Darshan */ #include <stdio.h> #include <string.h> int main(){ // Message to be encrypted char input[80]; // shift int key =0; int i; // Enter shift amount printf("Enter shift amount (1-25): "); scanf("%d", &key); // enter message printf("Enter message to be encrypted: "); scanf("%s", &input); for(i=0; input[i] != '\0';i++) { // check if letter is captial or lower case if (input[i]>='A' && input[i]<='Z') { input[i] = (input[i] - 'A' + key) % 26 + 'A'; } else if (input[i]>='a' && input[i]<='z') { input[i] = (input[i] - 'a' + key) % 26 + 'a'; } } printf("\nEncrypted message: %s", input); printf("\nstrlen(%lu)", strlen(input)); getchar(); getchar(); return 0; }
