Program to Counting and displaying occurrence of character in a string?

Answer 1

Since this question appears in both the C and Java sections, I'll give you the (slightly different) answers for each.

In Java

final String str; // the string we want to search

final char c; // the character we want to search for

int num = 0; // the number of times c is in str

for(char ch: str.toCharArray()) {

if( ch == c ) {

++num;

}

}

// num now equals number of times c is in str

In C

const char* str; // the string we want to search

const char c; // the character we want to search for

int num = 0; // the number of times c is in str

// loop vars

int i;

const int end = strlen(str);

for(i = 0; i < end; ++i) {

if( str[i] == c ) {

++num;

}

}

// num now equals the number of times c is in str
