Hi

This is programing in C not C++

find the error in each of the following program segments and explain how to correct it:

a) char s [ 10 ] ;

strncpy( s, \"hello\", 5 );

printf( \"%s\ \", s );

b) printf( \"%s\", \'a\' );

c) char s [ 12 ] ;

strcpy( s, \"Welcome Home\" ) ;

d) if ( strcmp( string1, string 2 ) ) {

printf( \"The strings are equal\ \" );

}

Solution

Qiestion a:

a) char s [ 10 ] ;

strncpy( s, \"hello\", 5 );

printf( \"%s\ \", s );

Answr: Issue here is with method name strncpy and parameters

it should be strcpy and also parameters count should be in this method is 2 but in our case 3 which is wrong. Please find the below corrct code.

char s [ 10 ] ;
strcpy( s, \"hello\" );
printf( \"%s\ \", s ,5 );

Question b:

Answer: Here is the issue with control string. we said control string string but define character in value.

Correct code should be either printf( \"%s\", \"a\" );or printf( \"%c\", \'a\' );

Question c:

Answer: We define character length as 12 and also assigned the string with length of 12. Generally we should define a char array length with 1 extra location pointer character \'\\0\'.

Code should be

char s [ 13 ] ;

strcpy( s, \"Welcome Home\" ) ;

Question d:

Answer:

Corrected should be

if ( strcmp( string1, string 2 ) ==0 ) {

printf( \"The strings are equal\ \" );

}
