Please, z is returning zero. Would love an explanation with a fix.Code:#include <stdio.h> #include <stdlib.h> int main(void) { char input[100]; int z; printf("Insert string: "); scanf("%s", input); z = atoi(input); printf("%d", z); return 0; }

This actually isn't what I want. I wanted to write a program to convert CHAR into ASCII code.
I suggest you post the input with the output you want because what you stated is not clear to me.
To me char is already ASCII!

Perhaps you want to print the value of each character?
Code:#include <stdio.h> #include <stdlib.h> #include <string.h> int main(void) { char input[100]; printf("Insert string: "); scanf("%99s", input); for(size_t i = 0; i < strlen(input); ++i) printf("%c = 0x%X = %d\n", input[i], (int)input[i], (int)input[i]); return 0; }
convert CHAR into ASCIIC - Type Casting - TutorialspointCode:#include <stdio.h> #include <stdlib.h> #include <string.h> int main( int argc, char *argv[] ) { char input[100]; printf( "String: " ); scanf( "%s", input ); for (int i=0; i<strlen(input); i++) { int z = (int)(input[i]); printf( "%i,", z ); } printf( "\n" ); return 0; }

atoi & scanfCode:#include <stdio.h> #include <stdlib.h> int main( int argc, char *argv[] ) { char number[128]; printf( "Enter Number: "); scanf( "%s", number); int z = atoi( number ); printf( "%i \n", z ); return 0; }

Looks good, thanks to all those that helped! Great to be back on the forum!
